In this case, GNU Go will believe all liberties have been
filled, so the opponent's last move either fills his own
territory, in which case it is definitely safe to continue
passing, or it adds a stone to a dead dragon. In the latter
case, to generate a move, change the status of the dragon
to ALIVE then generate a move. This should produce an
endgame move blocking off territory, hence tending to
surround the dragon that's trying to come back to life.

I see nothing wrong with taking it into account if the
opponent just added a stone to a dead dragon, particularly
if we are ahead.
