new hybrid double palm move in VF4 with Lau ?

Hi Vf fans around the globe,

yesterday I discovered some kind of Hybrid double palm with Lau. I still don't know how I did it and maybe it is a bug or maybe it is already discovered but this is what happened

I stood some places away and almost finished my friends opponent Lei. so I thought lets wait and charge my double palm.
at the same time my friend who played Lei was coming to me
and in some kind of shock I released the buttons. and now it happens. Lau was side stepping but at the same time he was making his double palm move. it looked so weird, because normally for a sidestep move you just press up and then a technique, but now Lau did it at the same time! I first could not believe it, but when I saw it back in the replay it really was true.

did anybody else had this experience? because I can't get the move to work again anymore.

 

on what version? ps2 or arcade? ive done summing like that, just b4 its charged all up! but i dont play lau anymore
