I figured it was something to do with Purgatory itself. Remember Benny said something about not having the thirst for blood there, and it returned when he went back to Earth. Maybe in Purgatory, not all monster powers or immunities are in play. Some kind of level playing field? Why would Castiel still have powers? The first time, Castiel and Dean were dragged in by Dick Roman's death to get there. This time, portal. Generally, angels wouldn't go there when they die. They might be sent there on tasks though, errands to run with their powers intact.
