marlon,
There are only three foot positions in Traditonal Yang Taijiquan. - Bow Stance, Empty Stance or Horse Stance. If your feet end up in any other position, your stance is incorrect. "Step up to Raise Hands" is an Empty Stance (i.e. Heels on either side of a line). You then transition by turning to the left and stepping into Horse Stance with the right foot. The stepping with ther right foot gives you space to deliver the shoulder stroke. The left foot now needs to be repositioned into empty stance for White Crane. These are the only steps I see Fu Zhong Wen taking during this process from Raise Hands to White Crane. This is the way I do it and this is the way Yang Family teach it. Am I missing something?
Very best wishes
