Admittedly I couldn't open the video. It requires software that is not in running shape on this PC. But from the picture, it seems awfully dependent on the situation - a handy dock of the right height, good balance and flexibility on the part of the paddler etc.
The pole could help with pulling up. But it doesn't seem to totally fix the issue of transferring weight to the dock. I don't see anything that stops the kayak from sliding sideways while the paddler is still hanging valiantly onto the pole and risks whacking their head on the dock.
