Not only did it carry over, but it seems like it was uncapped or something. I went through 18-20 goldsmith and 20-22 marauder with rest XP (all of goldsmith was just redoing the same recipe, mrd had a bunch of quests in there that probably extended it) and I still have over a full level of rest xp somehow at 22.
