That's because DISPLAY needs to point to where sshd wants it go! To
quote from 'man ssh':

    The DISPLAY value set by ssh will point to the server machine, but with a
    display number greater than zero.  This is normal, and happens because
    ssh creates a ``proxy'' X server on the server machine for forwarding the
    connections over the encrypted channel.
