This is a fairly technical question and there might actually be a name for this phenomenon it but I haven’t seen it discussed yet.
Meaty attacks on wakeup only leave you with 3 options: block, evade, reversal. You can do normal attacks because there’s no “gap” to allow any moves - you wakeup into the opponent’s attack. You can’t even crouch. However, blocking seems to shorten your wakeup by 1 or 2 frames. If you wakeup into a meat and hold down, your character will still be in a standing-hit animation. If you hold down-back, your character will go into a crouching-hit animation. This means that the game must be cancelling at least one of the wakeup frames and going straight into blocking. This technique is also the only way that I know of to get counter-hit out of a normal move by a meaty attack (not throw). So it seems that if you block while you’re rising, it cancels one at least one frame of wakeup, and it leaves you a gap to start a move.
Are there any uses for this technique? The only thing that I could think of was that it maybe allows you to Focus Attack 1 frame faster on wakeup?
