I think I read in some Prince biography (though I can't remember whether it was pure speculation on the writer's part) that it bothered Prince that he could play all the other instruments needed for a funk/R&B track, except for the horns. Obviously he was a person who liked to be in control of everything, so maybe he preferred sax players (as well as trumpeters and trombonists) who would bend to his every wish rather than having a unique instrumental identity themselves?
