Next question: does that gasket get pinched between the mating faces? Or does it slide down the walls of the alternator body?

Curious because it stands up rather than laying flat like a washer. The gasket that came with the alternator is too tight to lay flat (like a washer) on the mating faces so I dabbed it with super glue to get it to lay down…

Uhmm...

Superglue eats/degrades many plastics, oil based substances or causes brittleness. If you see any whiteness or similar discoloration you may as well start over with a new gasket.

Hmmm. I appreciate your feedback, but I'm not sure your statement is accurate. Have you ever used an o-ring splicing kit? You use superglue to splice the ends together. The whiteness is the hardened glue. But I will consider replacing considering

I believe the answer to the original question is that the ring gets pinched between the mating faces. I see on some alternator images that some alternators (like the original that came off the x5) have a small round o-ring that sits in a tiny groove. The oring that came with mine is like this:
