yeah as cool as that is, I would think that dismemberment you get with your glutes would count as its own hit since the foot you're using for the hook is also forcing ukes body to your glutes, which has its own momentum.
unless you can get the same dismemberment without it hitting your glutes, I would count that as 2 separate hits.
at least now we know that 9 dms in 1 frame is possible with that engine.
