We say:
"While an entity is associated with a dummy argument...action that affects the 
value of the entity or any subobject of it shall be taken only through the 
dummy argument unless..."

I think it is clear that all of this talks about execution on a particular 
image. "While" only makes sense when talking about one image and one 
execution sequence. The value of such entitities can be changed by other 
images, as we want of course. What is the problem?
