The director could have edited out one of those slaps but he didn't, it seems to me that Nolan told her to do that twice, first slap because she felt Bruce deserved it and second one on behalf of Bruce's parents.
To be honest, Katie fit the childhood sweet-heart persona more in BB, Maggie would have been terrible in her place, imagine Maggie slapping him twice.
And Maggie looked better as Assistant to DA who is a bit more mature than Katie in TDK.
So, I am not bothered by two actresses playing same character.
