What's the purpose of setting the left foot at address first then the right foot?

Actually, I teach stepping in first with the Right Foot with the Club in the Right Hand (and aligned with the Right Forearm to set up the Plane). And we had worked on that earlier. But, as we used to say in the church downhome, Keith had 'back-slid.'

At the close of the lesson, I was satisfied that he had worked out his own way to set his Feet and align his Stance. Also, he was now using his Right Forearm beautifully to set up his Plane and Impact Hand Location.
