I'm not sure if this is viable, or known about, or escapable. I play PC so I haven't had the chance to really test it with anybody online, but you can make the ex GS either cross-up, or stay in front (by choosing close, or medium GS). Execution isn't too tight which makes me think this could be used every once in a while to mindfuck your opponent.
