I’m assuming that there’s a release involve, but can’t see for sure. If there is a release, then this is illegal by rule 3.3.6.a.3. “3.3.6.a…Inversions may release to the following provided there is a spotter… 3. A stunt at prep level or below.”
Since this lands and stops in an extension, it violates the “at prep level or below” portion of the rule. It can be caught above the head, but only if it’s then going directly to the prep.
