Well I just had a Fridge Brilliance moment. We couldn't really make sense of the resetting of the leap. But if we think about it - they lost two days, which is how long Sam had been there. They were redoing EXACTLY the same thing that happened at the end of the B**gieman! It makes perfect sense, since GTFW reset the leap to undo Satan's influence in the B**gieman, the same thing SHOULD happen when Satan takes the reigns again
