Instead of walking in a circle, spin. Take a tiny step forward with your right foot, backward with your left. Then repeat. You are spinning counterclockwise when viewed from above.
Next, imagine holding a landscape photograph at arms length, and you initially facing a floor lamp. Now take that tiny step forward with your right foot, backward with your left. From your body fixed perspective, the landscape photograph doesn't move. It's the lamp that appears to be moving, and it moves to the right.
Next, imagine a helmet cam on your head that rotates to keep the floor lamp in the center of the camera image. From this perspective, it's the landscape photograph that appears to be moving, and it moves to the left.
That's what you are seeing in that youtube video.
