Darn, I would very much like a cookie right now ... wait what. Oh yes the question, err, so what? Each character in 3D fighters have so many moves we're bound to see a few repeats out there. Even in VF and Tekken there's still repeats among it's own characters like VF has Pai, Lau and Kage doing the same backflip also Jacky, Sarah and Kage also shared a backflip back in VF2, Tekken had the Mishimas doing the 1,1,2 punch sequence which btw is nice that they at least changed the animation for each character.
Also same thing could be said about when Yoshimitsu gained the roundhouse follow-up with a sweep which some characters already had in VF2. Same move in theory.
