Yes, or, then again, it does not really matter - keeping queens on also draws.
67...Qxe3!
The simplest way to draw.
68.fxe3 Kh6 69.Kf2 Kh5 70.e4 fxe4 71.Ke3 Kg5 72.Kxe4 Kg6
Every other possible move by Black also draws!
73.Kf4 Kf6
Believe it or not, it was also impossible here for Black to play a losing move.
