I am not sure what made you think this works, but systemd has no
concept of env var expansion in unit files. It's not a shell.

There's one exception: in ExecXYZ= settings there's env var expansion,
but that's really it. And it's expanded at the moment of execution,
i.e. not part of the unit file language, but of the executor code.
