Your Emporer
I'm not sure why you think that.
To me a vortex implies that the opponent is not just being reset but into a particularly bad situation, but this is just the same mix-up he can always do so really is just a reset/setplay. Without back block there just aren't enough possible defensive options in most cases that the opponent might have to make so you can't easily put him in a significantly worse position then if he were neutral.
