i am not terribly familiar with this technique, but in watching the video a few times, it looks to me that this is exactly the same as a regular knit bind off only using a crochet hook for ease. if you watch the way the yarn goes through the stitch and then the way it's pulled through the one on the right needle, to me it seems the same exact motion as if you were knitting and passing.
i do know that the crochet cast-on matches a knit bind-off, though.

Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? We were born to make manifest the glory of God that is within us. And as we let our own light shine, we unconsciously give other people permission to do the same. - Marianne Williamson
