Maybe because he wanted everyone to believe that this was the the last time they would see Batman.
Still doesn't make any sense, seems like that was just thrown in to make the audience think he died in the explosion and then later tadaaaaaaa he made it. That bit really annoys me as I expect so much more from Nolan. Besides there was only Catwoman and Gordan there both he revealed to that he survived the explosion before the film ends.
