Interesting vid.
Yeah I see a lot of SD styles that infight. Which is interesting that for mma it is considered more likely to get you knocked out or put on your back. Mma does infight as well. Either due to a tactical choice like I can wrestle better than I can strike. Or an environmental choice. Like I run out of places to go.
SD styles in fight or spend more time on that aspect I believe because most encounters end up there or start there. I believe it is natural for sport forms such as MMA, MT, sport karate, boxing etc. etc. to spend more time in a longer range because you naturally start out at a longer range since it is mutual combatives.
Then the rules of the contest dictate how much time is spent there (or in any range). As in like kick boxing or boxing where throwing and take downs aren't allowed, more time is spent on developing the stand up "in fighting" game, where as in MMA since you have the take downs and such it is unwise to spend a lot of time there.
For instance in this clip of Demetrius Havanas who was a great kick boxer and had a good "long range" and "inside fight" game plan, he didn't have to worry about throws, knees or elbows so his inside fight was blasting the body with the basic body hooks then going to the head. Then let the guy go and do it again.

The lean away is very common. The guy I spoke to has been changing his mind a bit about kicking. But at the moment is settled on a more karate styled front kick to round kick rather than the Thai style constant round kick. If they strike then you shouldn't pump with the handvto keep your guard up.if they shoot then pumping is better to defend the takedown. If the round kick hits more bent than normal the kick itself blocks the takedown. But you can counter that by pushing the knee across.
Not being an MMAer and coming from a more karate type back ground, I would stick with the MT type round house kicks more so than the karate type straight line front kicks morphing into the round house kick. If this was the type your speaking of which kick Machida used in the clips we've both posted.
In the clip I posted on Machida; he appears to be using that kick as a set up for his technique, or an interruption to the opponent's technique, or perhaps as a peppering type technique to cause the guy pain and make him think twice about the distance. Anyway it appears that as the kick comes in it twists at the end which is why he caught the outside of the first fighters knee with a straight line kick.
In the first vid you posted (Machida vs. White) when I saw the kick I thought it looked wrong and he was off balanced, due to his body position, when I watched that vid that I posted and the person who did that vid. pointed out the lean as a counter, that peaked my interest because then I thought, OK it was intentional.
In this vid of Jean Yves Theriault a kick boxer from the 80's/90's who dominated the sport as well as the vid. on Demetrius (above) when the guys are kicking they are in a much more upright stance allowing the kicks to be sharper faster and the kicker to stay in balance. That type of front kick, pivoting into the roundhouse kick, was what was taught to me in the sport karate/TKD (back then) and it works well in these formats because of body positioning as well as the rules of the game.

However in the vid you posted above at 6:45 where Machida gets taken down, the reason he got taken down was because he was (it appears to be) off balanced, due to his body position and how he applied that kick. 1) He was in a wider lower crouch and the opponent was farther away so he had to really reach for it and over extend. 2) He had to thrust forward using his hips facing semi front then twist so they go semi sideways to arc in the kick. This isn't a problem as the kick boxer's apply it, but in the lower stance I believe it becomes problematic since when he kicks he is leaning his body back to avoid the counter punch. Slow down the Machida vid. and you can see that he starts to lose his balance when his opponent taps or hinders his kicking leg on it's return as the punch is being thrown (but before any connection is made).
All of this to say that rules of the game dictate what can be used and what strategies rain supreme. MMA as the sport has evolved and has changed what works and what doesn't in the ring (such as your statement about in fighting, and where in kick boxing "in fighting" is something that was used quite a bit and very important). Balance and body mechanics are still vital.
If you kick after successfull strikes then they are unlikely to shoot at all. If they are backpedalling you may not be able to shoot. Because they can backpedal more quickly to avoid it. ( and use circling and evasive footwork)
Why? Not that I disagree with your statement, I just wondered your thoughts on why this is so.
The shoot itself you don't catch the leg but a kind of knee tap.

Mmaers have a whole system pretty much dedicated to not being put on their back. Due to the extreme suckyness of having someone sit on top and punch you for five minutes.
This was an interesting vid. and thanks for posting it. It reminded me of a judo throw, I've seen where the leg is swept by your leg, similar principles involved I believe, but here the guy is using his hand, never thought of that.
