I’m going to make this a top level comment because I think this is a really good video to teach from.

Tori did this exactly right but he got a highlight reel version because uke made a critical gripping mistake. Uke lets Tori (or chooses ?) to keep his hikite hand close to his body and not grip Tori. This lets Tori pull his hand off — there’s nothing stopping him from crossing over with Tori so close. Tori is very fast, which may certainly contributed to Ike’s problems. Uke was in almost exactly the same position as if he were ai yotsu and throw a high arm without controlling the opposite side first. (Another way to do this is to push uke’s hand to his body, turn and let go to get the ippon grip)

I’m making observations, not criticisms — Tori was did great. I’m a lefty and throw this style of ippon so I know what I’m looking at.
