The logic in this theory is flawed. Once there are only 2 doors remaining, there is only the possibility of 2 outcomes and not 3. Therefore, the original matrix of 3 possibilities is no longer valid once there are only 2 doors remaining and therefore considering the 3 possibility matrix at this point is completely invalid. Once there are only 2 doors remaining, there are only 2 possible outcomes and therefore the odds are 50/50.
