We once had a fellow in our basketball team in primary school that would fall over after every... single.... shot he made. Fadeaway shot? Understandable to fall. Normal standard shot? FALL! Lay-up? FALL! 3 point shot? FALL SOMEHOW!
I was just like "Dude! Stop falling over!" Well, didn't say it but thought it. I honestly think he was just doing it to be dramatic and make it look like a cool shot.
Anyway, some of those kicks looked like sacrifice kicks, which may just be part of the ruleset he's used to. In Kyokushin knockdown tournaments, the kaiten mawashi geri ("torso turning rotating kick" or "Rolling Thunder kick") can be super effective if done properly, but in the ruleset if you fall, they reset you both, so they can afford to do this.
But some seemed like he was just emphasising speed at the expense of root, which again, is good for some rulesets, and not so much others. I dunno. I'm just speaking words at this point. *falls over*
