If you can get any fastpass with the 4th rotating fastpass, then people might only schedule the 1 top tier fastpass and not the 2 other second tier fastpasses.
Or, if they are forced to schedule the 2 other 2nd tier fastpasses, then they might try to cancel the 2 second tier fastpasses when at the parks to get access to the 4th rotating fastpass.
