Debian does not use tmpfs for /tmp by default. The unit is placed there
because it's intentionally not in use unless you enable it (and not
just by "systemctl enable", I believe it's done this way to prevent any
dependencies in other units from accidentally activating it, possibly
at a moment when it would hide already existing contents of /tmp).
