it would have made it harder for him to leave if he'd been victorious, but being locked in anywhere has never stopped Batman.
I actually wonder now, if "You've made a serious mistake" was in regards to her believing that she could save herself when dealing with Bane. And she interpreted it as "I shouldn't have led him to Bane" (like the audience surely did) instead of "I shouldn't have thought I could negotiate with Bane." Although we do see her trying to flee immediately after, so maybe she got his point too.
I mean, Bruce really did have a death wish at that point, and expected only one of them to walk out of that fight. If Selina hadn't led him to Bane, he would have found another way. She just happened
to be the most convenient avenue. Perhaps that's why he isn't all that angry with her when they meet again.
