Well it does not always perfectly stop but it does slow down a lot.
I do this pretty naturally because I learned this as I did discus throwing. In discus throwing you learn to pull the left elbow back and down into the left rib and then suddenly stop that motion to create a "block" to throw against.
this pulling first accelerated the left shoulder and then fixes it so that you have something solid to pull against.
you can also feel that the shoulder rotation is increasing the stretch of the pec which is also slowing down the shoulders (till the arm stys back like an anchor).
this is the kinetic chain
