I expected the ending the second they said that his totem used to be her totem. It instantly defeated the whole purpose of the totem, knowing which world was real because only you know how the totem feels.

The idea also had the flaw that it would not work in a world your own mind created because you know the totem already. His mind could be stuck in a trap, where the old man is the boundary that redirects him back into the maze of the world he thinks is real. If the limbo is his own subconscious trap, the top will only fall over when he believes he is out of the dream.
