Advies slow it down and watch again, first footage from 0.0s. Kicker pushes off rear foot, strangely rear foot touches, then front foot touches, kicker flies through the air and rear leg touches again just before kick lands.So looking again appears to be 3 stage movement, 2 jumpy steps and then the kick.
I would call it a pretty different approach to punching in WSL VT, and would be slower and more telegraphed in my opinion. Not to say it wouldn't work, but not really doing the same thing
Watch the second video. When done it really is smooth and fast and not multiple steps as you seem to think. Please post a video of the comparable WSLVT punch from a long distance that you have been referring to.
