H'm, I didn't think it was ambiguous, although I did say "the engine" a
couple times when I meant to say "kgsGtp". Anyway, here it is with that
fixed and a little bit of wording changed:
        If the engine and the human disagree on the status of living and
        dead stones at the end of the game, one of two things will
        happen: If the game uses non-Japanese rules and the engine
        supports the kgs-genmove_cleanup command, then kgsGtp will
        recommend that the human press "undo", after which the engine
        will get kgs-genmove_cleanup commands (in place of genmove
        commands). In all other cases, kgsGtp will simply refuse to
        finish the game unless the human agrees to the dead stones that
        the engine listed in its response to the final_status_list
        command.
I hope that is clear. The kgsGtp documentation has more information in
the section where it lists the way that each GTP command is used.
