{Mate is not model, the square d3 being (like e3) controlled by both the Lion a3 and the neutral Empress f3.
Neutral Camel cannot run away, because the check is double, given by both the Lion and the neutral Empress.
And the King cannot capture the said Empress, as she would have to be posed so that she intercepts the Lion, but she would still give check, as a Rook.
