I'm missing something. When I first came to this site with my DD's swing I was told she was ABAF.. basically she was swinging and shifting at the same time. That sounds very similar to what you are describing. And I know that I am not piecing all this together, I know you don't subscribe to an ABAF swing, it's just how I see and understand itLol! Very similar conversation... Complete opposite of ABAF. Much of this boils down to how weight distribution is understood. The movement of COG and pressure at the ground are different functions.
Also executing launch prior to toe tap does not seem the most effective. JMHO, I come back to the athletic posture/position. I think about throwing a ball.. I would not want to make that movement(arm coming forward) prior to foot plant.
