Interesting. It looks to some extent like the irimi-tenkan og Nishios Sensei except He would do it from a more ai hanmi katatetori looking approach to have ukes balance continue forward and in a circular path. However from morotetori it is new to me. Main point must be to maintain the front towards uke and make sure kusushi happens from body movement and not from strength. This reflects on the interplay of atemi from right and left side with Tori. Worth exploring I think.
Here is an example of an omote version: https://youtu.be/XfheWg0WdVE
And in this you can see a lot of morotetori variations including some to an ura approach: https://youtu.be/MOdzF8mbi3Y
