I would add on up through the muscles attaching the lower torso to the pelvis. Would you agree?

Yes! Now how to use this knowledge to build momentum we can use in throwing or swinging.
This goes to Dixon's point I believe.

Does that makes sense?

Sort of yes and yes in a physics sense though that's not the whole story... but...I encourage you to read Dixon.
I see the legs as posts used by the muscles from the upper thighs to the lower torso to achieve using the butt as the anchor since we can't get the power from the ground to the bat quickly enough to do what we need to do in a little over a tenth of a second. Hope I'm communicating my intent here. A fabulous example of is Koufax throwing. Did the foot against the ground contribute/initiate. Whatever. Look what leads. His feet are certainly on the ground but there's a ballistic motion anchored by the butt if there ever was one.
