This is incorrect. Perspective is a function of camera-to-subject distance and is independent of focal length. In the above example, you can shoot from the same camera position with both the 300mm and 600mm lenses. If you crop the 300mm shot to give you the same field of view as the 600mm shot, the perspective will look the same.
