Thanks, that is what it was. I put the same user id on each machine.
When I changed one of the clients to use a different user id then it opened xfce4.
Note that this silly behavior is specific to XFCE4. In general, running concurrent sessions with the same userid is supported by X2Go (though some applications will have issues, like Firefox -rightfully- complaining that the profile is already in use).
For a workaround, please see: <https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1083#30>
