The fact that all of phil's cards are live has a lot to do with his equity in this situation. In addition, he holds the only spade flush draw.
However, as you should not put people on specific hands, such as assuming that the aces are split pairs, your equity range is fairly wide. If the flop is low, you have very little equity.
