Well, the way I usually do it is as follows; Do CD as soon as possible as to get the hit at the last possible couple of frames, you they try to reversal you with a special move, say, EX Iori, if he does a reverse DP, only the first hit will hit you and you will end up standing on the correct side, allowing for a full punish, and, if you get a counter hit, you can do a DM and get back in the same exact situation, allowing for a semi vortex situation.
