/run is used instead of /var/run, and /var/run is a symlink to /run. Within
a distribution RUNDIR is, kind of, hardcoded, no matter what is it.

So real question is to distinct usage of the plain RUNDIR and sub-directory
under it, as later one requires some special handling on memory based file
systems.
