I think he did.
He had to go to the middle of nowhere to disappear in BB, but here he was in Italy in a crowded cafe at the end of TDKR after faking his own death. If he truly wanted to escape, he'd go to some island or even the backwater areas from BB. That to me shows he'd eventually show up alive again as Bruce Wayne and not live his life under an assumed alias.
