It's fairly standard for Unix systems; as far as I can remember, Solaris, Tru64, and every other Unix-like OS I've come across does this, too. I can't think, off the top of my head, of a specific need for it to happen (since a user can't change the ownership or group of another user's file); it's probably done just to force an admin to confirm that they still want the file to be setuid/setgid when they alter it.
