Mage hahaha LOL, of course they work if they Ukemi XDDD.....for that they are called Ukemi Traps or Tech Traps XDDDDD......and yeah the combo is only guaranteed until the time they Ukemi
They are tech traps but only in this instance, a corner, and only works if they ukemi. So if they roll this combo is basically made ineffective. Still good try though.
the fact is, you say that you dont think they are tech traps in this video, and in minute 0:05 clearly the opponent try to ukemi, and is "tech traped" by leixia 44[A]
Okay, but that's only if they ukemi. Why the opponent would ukemi into the corner is just ludicrous. Most people would roll so its actually completely dependent on ukemis.
Mage, the tech traps are so obvious to see, when the stun combo end(no more sparkles in opponent) he clearly do a ukemi, that ukemi is catched by the nest hit, and in that instance the ukemi-tech-trap occur
