I've seen that video before, and the hadaka jime was effective. At the last as kime was achieved, it looked to me as if the forces were going both in and up into the jaw. That works, but as the video shows it takes a bit longer for the effect to develop. The force going into the jaw is painful and often the uke taps due to pain. If the goal is to get uke to tap, it succeeds with people who will tap.
