Yes, this is correct. I'm not sure quite how Tom's system ended up
with the links the wrong way around, but that's definitely something
which needs fixing. One situation which can cause it is if your
system was upgraded inside a chroot environment (i.e. not live), but
that's unlikely.
rm /run
mkdir /run
reboot [the scripts will fix up everything else at boot]
You can move stuff around and fix up the directories and links by
hand, but I wouldn't advise it since these directories all contain
the state of the running system, and many of them are kept open
by running services.
