Ok, here’s what I want you to do: concentrate on theanimated .gif on your top. You’ll quickly realize it represents some sort of see-through sphere, constructed of many dots rotating in one direction. Dots in front make the front face of the sphere, while “background” dots belong to sphere’s back. It’s logical they rotate in opposite directions. Now try and switch those background dots with front-face ones. Notice any change?
