The nose of his saddle is almost certainly < 5cm behind the bb (look at the vertical bar on the positioning bike - the forward edge of it appears to run right through the center of the bb, and his saddle is certainly in front of that; also, look at his bike in the background, there's no way to be 5cm back in the forward saddle position on a P3), and, in his stretched out position the ends of his aero extensions are > 75 cm from the tip of his saddle.
