You can't talk about "common sense" regarding a system where you have no knowledge or experience.
That's called guessing.
No. It absolutely does matter. Because if it's already part of the system, that's where it "came from", plain and simple.
This "outside of an MMA context" is an unreasonable loophole you're setting up.
Because it's a
Biu-ji tactic, "beyond the pointing finger", beyond the core VT method, it will not be needed in VT vs VT. It will only be used against other styles.
Here's the thing...
You originally challenged me to explain where this high cover is in the BJ form, because you didn't believe it was part of the system, and thought it not being in the form would prove that.
So, I demonstrated that
it is in fact in the form, with photos and ample explanation.
You then complained about the last photo, despite it being the exact same arm position as in the form and other photo, because it's done with one arm like boxers do.
But, you know as well as anyone else that VT/WC/WT forms use double-arm actions that are applied individually.
You then objected that the body and head position is different. But, of course we aren't restricted to fighting exactly like the forms. Things are used to meet whatever needs.
So, you then objected that the action in the form doesn't pause there even for a second.
But, you are unaware of what in TCMA is called
ding-sik, or "fixed positions" where flowing actions in forms can be paused and used as shields or the like.
The Shaolin example I showed also had a non-stop whirling action in the form, but applied the shield as a
ding-sik.
Laan-sau is an example in standard VT that can be held as long as necessary/practical to bar an opponent's facing while attacking them.
This cover at the end of BJ can extend out in large frame, as in the form, in a searching pattern to sweep the area and intercept whatever may be coming.
Or it can be done in the small frame, as in the still images above, to shield the head and come straight back to fighting guard or striking.
Obviously, when not recovering from a ducking position, when upright and looking forward, there's no need to extend and sweep a zone while recovering position. We can simply cover tight and go straight back to attacking.
Like I said, you can't learn VT, or any TCMA, by watching video. You need to have the actions explained to you. They are often not obvious.
So, I have demonstrated that the action is in fact part of the system, in BJ. You are just unfamiliar with how the system works. Not a big deal.
Your next objection seems to be that only Sean's group does it, and they're Europeans, so it doesn't count.
You want to see a WSL student doing it, but you create the loophole that it must be VT vs VT, which generally wouldn't require this type of action.
So, ruling out your unreasonable loophole, you did say this:
I don't know why you're still saying "might be", if it has been clearly demonstrated to be in the form, and WSL's direct students do it. What other objection or loophole might you be holding out? And why are you so opposed to it being a legitimate part of VT?
Anyway, here is a WSL 1st gen. student, Cliff, teaching it to a child in sparring drills, then using it himself in play sparring, both in double and single-arm form.
You might make this about his overall performance. I don't think it's a great example of VT sparring either, but the point is you asked for video of a WSL student using it. So, here you go.
It's in the form, multiple groups do it, including 1st gens and several gens down the line, Europeans and Chinese alike. What reasonable position can you have to say it's not a legit part of VT?
If you want to continue saying it came straight from boxing, as opposed to other TCMAs, or simply being a refinement of the natural instinct to cover one's head that numerous unrelated styles have come to on their own, you need to provide proof or evidence to back that claim up... or just acknowledge that it is a legit part of VT, like many other TCMAs.
