I have seen that episode. I have trained on that very open city area in the beginning of the clip. That is Ernesto's son Jon-Jon.
I have seen many film clips of huge numbers or performers doing double stick drills with very thin sticks and choreographed dance steps. They say that Filipinos, like so many cultures had to hide the fighting moves inside things like dancing when under the control of various regimes. As fighting practice was outlawed to prevent the growth of fighting skills for any rebellion.
Ernesto has always mentioned this and these roots, but does not officially teach dance or teach this thin stick, dance show stuff. He sticks with the classic footwork patterns as they relate to martial arts footwork.
I saw that part where Jon-Jon was doing "standing center lock" or what the Japanese call Sankyo in the early practice style/progression of doing right lock, then stepping off doing left lock, then stepping off to the other. Classic V footwork really. The uke/victim is just a pliable wing chun dummy at this point in practice.
That practice was a Remy favorite and also Wally Jay of Small Circle JuJitsu.
Meanwhile Ernesto is VERY graceful and I'll bet he can really "cut a rug."
Football and soccer drills help a lot too. Makes me think of all the players having to take ballet!
Somewhere here on the forum is a clip of Alpine Germans doing chorus-line, dance steps with thin sticks. Where that came from?
