Seriously though, I think I just figured out how my original kali teacher seemed so good back in the day.
Ha! You see a similar thing happen with instructors who have developed a "counter" move to some technique that they teach their students.
A common example is an instructor 'teaching' a move like, say, a wrestling style takedown, then having a student perform it on him (at 'teaching' speed and power) and then using his counter on it to show that the moves not effective/his art has a counter for another arts moves. In this way the, say, Ninjutsu master can prove to his students that they he can defeat wrestling.
The flaw, of course, is that at no point did they actually interact with any wrestlers. The student(s) only interacted with their teacher, who showed them a move from another art performed in such a way that it is designed to be defeated by what they really want to show. That's where you get those funny sequences where the instructor says 'now grab my sleeve, no like this, no, like this!' because his "counter" only works one way.
MMA guys have said (for decades now) that wouldn't work on an ACTUAL practitioner of the art doing the move (like in Wiz's threads, where people say 'that wouldn't work against anyone who actually grapples/wrestles, ect). The counter has been, and will forever be, one of two responses:
1 - "We train for the streets!" Which really doesn't make any sense unless all you plan on doing in the streets is fighting your fellow dojo buddies.
2 - "We aren't (say) wrestlers, so we do it our own way/don't have to follow your rules!" Which makes sense, except that the move they just showed is supposed to be a counter for a wrestling take-down.
Anyways, it's a tried and tested system, and you can find examples of it in EVERY Bullshido video. From Aikido guys showing how to counter boxers and having an Aikido student do "boxing" moves the way the Aikido instructor wants them to, to Chinese Ninja's showing how to counter double legs.
