That's also my understanding, and I'm suggesting that it distinguishes
the two by checking if `M-.` is used consecutively or not (just like
`C-/` can't easily tell whether you want to keep undoing or you want to redo
the thing you just undid, so it checks whether these `C-/` are
consecutive or not).
