If I had to guess, it might have to do with the Mac standard of “save on close window” which is a vestige of an old apple desktop metaphor where every window represents a file somewhere. So you end up with a lot of duplicates from either trying to edit a read only document in some apps (which spawns an editable copy) or accidentally hitting duplicate (generate a copy of the current file in the same directory) which is the mac equivalent of “Save As”. It’s on you the user to move the new file where you want it.
