Yes, that's the expected behavior, and matches the behavior of Emacs-24.
Is that a behavior you like or a behavior you dislike?

Indeed, one of the differences in the new UI is that we don't have the
"C-u M-. lets you cycle among matches" any more.  Instead we pop up an
*xref* buffer where you can choose the match that interests you.  I find
this easier (and generally faster) to use.

This is an issue that only affects the UI (not the API and hence not the
backends), so we can easily fix it by providing either different UIs, or
some config var, or ...

Indeed, the ordering looks incorrect.  This is a bug.

But popping up the *xref* buffer when there's only one element in it
doesn't make much sense I think.
