And that is where his argument fails, as Alex has pointed out. If there were no further anomalous refraction, the angular anomaly would remain unchanged, from when that light-ray whizzed past my head, for as long as it continued to travel. I should add that I have no idea, at all, of the range of heights above the water surface over which anomalous dip occurs.
