Yes, it did need to be explained. This was not a case of being a stow away on a ship going abroad like in Begins. We're talking about getting back into a city that's sealed off by the army and has it's bridges blown. The whole point of it was nobody can get in or out.
So Bruce just casually appearing out of the blue like that needed an explanation.
