That sounds wrong. First, systemd is already cleaning /tmp, so nothing
good is going to come out of cleaning it twice. Second, doing cleanup
as unprivileged user does not really work. If the user is not running,
the cleanup is not going to happen, so on a multi-user system, when the
user logs out, files would stay around infinetely. So cleanup from
the graphical session is ineffective. More importantly, an unprivileged
user cannot access files without bumping their access time stamp. So
trying to do the cleanup as an unprivileged user actually interferes
with systemd-tmpfiles (see df99a9ef5bb7a89b92 and 
https://bugzilla.redhat.com/show_bug.cgi?id=1183684).
