I believe that it is a check to make sure that the page is not being displayed inside a frame.
The page that is doing the checking (self) is comparing it's URL (self.location) to the URL of the outer most frame (top.location). If the two are not the same, then the page is inside a frame, so it sets the top.location to it's address, thus removing itself from the frame.
