I am not sure I understand why you referenced Push Hands, let alone single-hand and double-hand versions. Wasn't the original post only about the hand form?

I understood the original poster to be using "official" in a different way. I thought he was using shorthand to describe the one application you should use for your intent when you do that particular posture. The implication is that every posture can be adapted to many different applications, but in doing the form, one particular application should be in your mind and shape the precise details of your movement.
Other styles seem to have a different application in mind during the transition into Cross Hands. Many of them have the hands open so that they end up spread symmetrically right and left, before the circle down into Cross Hands. The Association's form is not like this. We do it with the right hand doing something slightly different from the left hand. According to my understanding, the right hand will end up distinctly lower than the left hand as the weight settles into the right leg. I make them fully symmetrical only as I shift the weight back into my left leg.
