Oh ok, now I got it.
Last question on this. If I use L2+R2 and R stick to reverse sub a transition, can i still block the transition even if my timing is too late to get the reversal? Or is adding L2 a make or break decision as far as blocking transitions (i.e., you are either getting the submission reversal or nothing).
What I'm getting from this is that transition reversals can happen from half guard (passing to side control), or sprawl (escaping to standing clinch). On the other hand, similarly, but slightly different, you can reverse a take down with just L2 and R stick. The two get confused only because of the escape to single leg takedown animation which allows for a takedown reversal (L2+R stick down) rather than what might otherwise appear to be a transition submission reversal (which is actually is not)
Thanks, this is really helpful Haz, and whoever it was who answered previously. Really appreciate it.
