<font face="Verdana, Arial" size="2"> Since Yang style, despite changes in emphasis plus name changes, essentially follows the identical sequence of Chen style, I would have to say that they should probably be viewed as separate techniques. Ward Off Left probably having been modified from Buddha Warrior Pounds Pestle, and Ward Off Right from Lazy Tying Coat. These movements in Chen style are performed in the same directions as the modified Yang style moves.</font>
That is an excellent point. It can also explain why Ward Off, along among the four straight energies, gets to be represented twice in Grasp Sparrow’s Tail.
The counter argument could be that whenever Ward Off Right appears in the form, it is preceded by a named or unnamed Ward Off Left. Although it is probably not directly relevant, is this also true of Lazy about Tying Coat in the Chen Form? Is this always preceded by Buddha Warrior Pounds Pestle or a similar posture?
