I don't recall exactly how this feature works, but it doesn't see the
command line of the other machine at all.  I believe it simply checks
the current X server (which, when you're using ssh -X, is the local
machine you're sitting at) for a Firefox window.  If it finds one, it
tells that window to open a new window rather than starting a new
process.  Details may not be exactly as depicted here, Google for the
most accurate information :)
