These are legal. They “look” like a flip, but they are not. They are the technical/rule equivalent of starting in a straight up and down inversion that releases to a cradle, which is legal by 3.3.6.a.1.
The hand on the shoulder remains on the shoulder until the top person is basically upright (hips are over the head) and inverted. Therefore, when the top person is released, the hips don’t THEN pass over the head. They are already over the head. That means it’s not a flip by definition.
From a general safety standpoint, these are pretty simple and don’t have the kind of height that would cause the rule committee to be concerned.
