What is the purpose of the U-shaped grasp? Wrestling away a stick? If so, why is the next movement performed in slow motion? A more plausible interpretation of the set is a throw via lifting and dumping the opponent on their head. It is particularly useful against a side headlock.

In looking up side headlock defenses, I've noticed that few include both the face push and leg scoop (that's why the Waza Wednesday video was a fortunate find) but several include one or the other. This defense uses the face push. This defense uses the scoop and lift.
