That's a hand-wave explanation. The real reason is they would have to put work into adding XP for all the mobs and bosses in all of the level 50 dungeons that previously had none, and they didn't want to spare the development time. They could've picked a better excuse, as the one they chose is the WORST reason ever conceived.
