Could it be that this plane was already given some software update, so that United could do their own testing on the flight back to Arizona?
I'll make a wild guess: The plane has to undergo routine maintenance on a periodic basis which UA chose to do at their MCO base. Afterward, the plane was returned to desert storage.
