I'm not certain why both the OP and the guy in the video are so far forward on their saddle.
ISM saddles look like they have noses but don't. When properly set up, it looks like the rider is far forward while actually riding correctly. IIRC, ISMs could be much shorter than they are, but they added superfluous material at the back to meet UCI requirements. Their docs say that the back 2-3 fingers' width should be visible when riding.
