Ha, failed attempt at humor, I was trying to poke fun at the video. "That guy" was supposed to refer to the dude in the video bouncing around. I know your alias!
But the video is a little interesting, in that it is reminiscent of how my last teacher would "fa". The particulars are different but the idea is the same; that is, the bigger and more dramatic the movement the "more powerful". It took me awhile to realize that the situation is quite the opposite.
