Same tee height and location, Donaldson demo on the left, Donaldson Actual swing on right. Donaldson's initial movement is "down to". What we see Donaldson demoing below is more of an outlier IMO. He doesn't get into this position. Real swing on right shows barrel still above the hands and he's progressed further in his swing as you can see with the turning of the back hip.
