RC Hop

So…

I was playing around in training mode with RCs yesterday, seeing if I can do it on the PS2 Classic PS3 version…
And I noticed something.

You can input

:lp:+:lk:
:mk:+:hk:

You don’t need to input the LK again, as the negative edge off of the LK is buffered long enough for the input. or at least… that’s what I assume.

Anyone know why this works?
