I think the same thing will happen with xfce4-terminal once the first
window is opened (see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=710002 for example).

xfce4-appfinder is actually run (as xfrun) as part of the session
startup in order to start fast when you call xfrun. That also means the
window will inherit settings of that process, for example the $DISPLAY.

I'm not too sure there are ways to workaround that. I'll forward the bug
upstream but in any case, you have to know that multiple $DISPLAY is not
usually something really supported when it comes to dbus-activated
