Wrong. Left side tech makes the JF O JF O just much harder. That's why you always need to train with Left Side tech on with Alpha. On little hitboxes (Pyrrha, Viola, etc..) timing is very strict. You can have another version of 44B+K BE 214~3B:B JF O that is combo and makes 81 dmg but doesn't combo with another JF O if you're too late. But still IIRC, 44B+K 214~3B:B JF O JF O it can't be teched. Even with Pyrrha. Timing is very hard though, so I prefer 44B+K BE JFO JFO.
