While I obviously think Brecrow's theory is fallacy, I have to agree with him that the analogy the two if you are using here is just as flawed.
The airliner (= airmass container = wind) is flying WEST at 500 knots. The person is initially walking East (1 knot airspeed, -499 groundspeed) turning around to West (1 knot airspeed, 501 knots groundspeed).
