Thank you for your question. The couple of movements that relate to this total motion are intended to build the energy throughout the whole motion with the focus being on the ball in the hole and the step toward it. When playing on the course, although practice strokes might not be required, it would be advantageous to look at the hole as you get setup and aligned. Again, these movements are intended to introduce you to the flow and connectedness of the whole motion and how simple it could be. Great observation though and thank you for your question, it is our hope that others can learn from this as well.
When playing on the course, the step to the hole after every stroke is not required on every putt either. We do want the mind and body preparing for this step so when the ball does go in you are already stepping toward it as an extension of your stroke.
I hope this helps. Thank you for the time and energy you are putting into the training!
