Short answer: That's why I asked the question.

Long answer: Depends on what you mean by "thing".

It is true that these two paths point to the same place now, but
/var/run is only kept for compatibility with software that expects this
path to be available, so we, the packagers, don't have to patch all of
it now.

The mountpoints, however, have an obvious but important difference:
/var/run requires /var to be mounted first to work correctly, and /run
does not — so the latter path is more simple and thus preferable, and
the former path was a mistake.

The discussion probably went over my head then, or was private.
