This is why he got such a rush out of fighting ichigo, then again at noitra, and so on, so forth. He's been looking for a fight where he could nearly lose, and everytime he was retardedly injured, he'd release some of the "shackles" they mention, to make sure he was never full-on blown out; to make sure it was a good fight, but he still won. Now she's fucking his ass up and healing him so he'd realized he just missed something she did, and try more, and more, to ensure that the fight was somewhat winnable, which is why he's getting stronger and stronger.
Telling him that he's been gimping himself won't mean shit if he doesn't know he's doing it; he still thinks he's strong as fuck, and it wasn't until she ganked his ass in the throat that he realized he's become weaker.
