Yes, that seems to be the logic.

But does xref provide a command to jump to the next match without going
back to the *xref* window at all?  I looked through the code, and I
couldn't find it...

Oh, it's just `next-error'?  Well, that makes sense.  I'll just rewrite
the code to be xref-find-tag-other-window/next-error.
