That's only because, at least with the G4 AGP Graphics that you refer to, it's just about impossible to physically attach the drives to the cable in any other way -- at least in any way that's as easy as just switching the locations of the two drives. I don't know if there's any advantage to having the boot drive as the master, except that if both drives are bootable the master will, I think, be the drive that boots until you tell the computer otherwise.
