There's a specific distance where if you combo them into the corner but hold back on the B Coup, you can use EX Mirror afterwards and it'll show up just behind them, offscreen. It'll slowly travel towards you and hit them from behind, which gives you a chance to hit them with j.B or whatever else you want. It's really range-specific (if you're too close the mirror will be too far away and they'll probably hit you before it comes on-screen) and mostly a gimmick but it catches some people off-guard.
You can also do it after a (counter-hit) DP > Bufudyne, but you have to sweep feint once first to adjust the range. It always shows up in the same place on screen, it's just a specific distance you kind of get used to after a while. Eventually you'll get a sense of when the opponent is in range and when they're not. It's just short of full screen, about the same as the max range on 5D.
