Photoshop Mock-ups touching shoulders

Edit Post

When you see mock-ups, some pictures have people crossing their arms and touching their shoulders, while others have their hands hanging to the side in a natural position.

My question is; Do doctor's use tricks to make your mock-up proportions look better by having you pose with your arms in different positions?   Are they trying to make you more optimistic about lengthening more?  Seems like they end up choosing only the best arm position to hide your particular disproportion when you lengthen your legs.

Appreciate any thoughts on the matter.....thanks

Probably true... but not sure.
