That's not my understanding of what's going on.  There doesn't need to be
an X session running on the _remote_ machine. but there does need to be
one on the _local_ machine; then X apps called from the remote machine run
on the local display.

That configures the remote server. You also need to have

ForwardX11 yes

in your local /etc/ssh/ssh_config, which configures the local ssh
client.  Or run "ssh -X ...." locally.

Or at least that's how I understand it.
