Well he would not have been able to land a killing combo after the CH BE, so the reset makes sense. The 6B was definitely not hit confirmed though.

FUCKING FINALLY. Now I can actually practice shit and test shit out.
On the subject of bursts, I believe they wanted them to be more like GG bursts. In other words, you needed to commit (or commit like 95%) to baiting the burst, rather than just doing some burst safe combos (that a lot of characters had) that weren't 5A j.AAAAAA while holding back.
