Right, it does re-use the session from the shell `service lightdm
restart` was invoked from. But there's no difference if that shell comes
from a ssh- or from a local login.
Here's `loginctl show-session` after I did the service restart from tty1:

And here goes another experiment: To circumvent that whole systemd
session hullabaloo, I added /bin/bash to /etc/inittab like this:
------------8<----------------
8:S2:respawn:/bin/bash -il >/dev/tty8 2>&1 </dev/tty8

Doing the service restart from tty8 brought up lightdm with a fully
functional user-session:
