the hips have moved forward more and turned more degrees on the backswing, thereby resuling in a greater degree of freedom for the shoulder turn. the 2nd tilt(spine angle is more vertical at the top of the backswing and the shoulder turn is more centered(comparison of 1st pictures). the left shoulder is more forward as a result in the comparison of the 2nd pictures and the 2nd axis tilt is thereby less as it was a function of the backswing.this is also noticable in the tilt of the shoulders in the first picture on the bottom. the reduction of the 2nd axis tilt combined with the overall cog more forward will slow the rate of closure of the clubface at impact. as both lower and upper centers are more forward the hips press upward reducing the the flex in the right knee impact and next to last pics on bottom). this sequence is far superior to the lower and some sophisticated instruction wet into changing those pictures
