They don't put "anything" on those routes, the depot try their damn hardest to put the correct route branded vehicle onto that route.
The reasons why you've seen non-MAX vehicles on the X14/15/18 is because they're were no MAX vehicles at the time or the MAX vehicles were being used on the Sapphire X21/X22 from the start of the day.
