One reason I can think of would be to illustrate to the audience that a
window exists. Beyond that illustration I'm not sure of any advantage in
having it somewhere different than the screen. Without seeing the images and
the effect of the artificial window placement I wouldn't be able to
determine much else. Is the artificial window special in some detail like
providing a shaped outline?
