I find it highly unlikely, however, that they would use the exact same image: they would change /something/ about it, whether it just be what the wallpaper is, to the angles of the shots. Given that this is actually the same filename being shared from the other product, it seems much more likely that they haven't put the final images in place yet.
At least for the computer icon in Mac OS, they haven't historically changed without visible design differences. I doubt they would handle iPhones differently.
