ssh -X also sets up a new X-server (default :10.0).

The ability for remote (including VNC) executables to access an X
server has been part of X since its inception in the 1980s.

<HINT>
If you wish to use the same X-server,
you simply need to inform the executables to address the same X-server.
This is usually done with the --display option or environment variable
DISPLAY.
The address is "<host-or-ip>:<server-no>.<screen-no>" .
Note that you will have to open up the appropriate firewall channels
on BOTH hosts.  Typically this is ports 6000-6030(?).
Use "bash> xhost +<host-as-reported-to-X-server>" to authorize access
to the server.
You may need to copy appropriate ~/.Xauthority cookie to the remote host.
</HINT>

See X(7) for further details.

Hopefully helpful,
