Well you can speed past the repeated dialogue with the fast forward button, and each time the dialogue slightly changes to fit the scenario, so I guess that part is somewhat filled
I'll explain further: Waiting 40 seconds while already read dialogue flashes in front of your eyes isn't very interesting for players. By altering or shortening dialogue you offer players something new to make sure a player doesn't have to wait for new content. Waiting isn't considered to be fun in Games.
