Yeah, that's a bit confusing and a good question. We use a decision directed equalizer inside of the receiver to track the residual frequency error from the synchronization methods. The blue points represent the pre-equalized values and the red the post-. You'll notice that the blue points will slowly spin as the symbols progress while the red dots stay locked to their constellation points.
