Wow! Great observation! OK, how's this:

a) she saw them put something in their pockets (not likely)
b) she obviously sees that "something" is in their pockets. The 
pockets themselves are visible, they're bulging out or something. 
There has to be something there, and she knows it (more likely)

For example, if a wizard saw a tablecloth over an obvious object 
underneath, that person could Accio it into his or her hand. Of 
course, this could be verrrrry dangerous. It could be a bowling ball 
with teeth or something.

It would be different if there was an object in a tablecloth in a 
room not in view. Then there's nothing there as far as the person 
knows, hence, no Accio.
