If Norris had immediately relinquished the position, then I think you'd have a good argument that Max then had the lasting advantage by having left the track to enable him to keep his position.
I don't think the argument holds water that subsequently benefitting from another driver's punishment you yourself received a lasting advantage that deserves it's own penalty.
But that is rather perverse reasoning. If the stewards were going to adjudicate that Max was in the wrong and should give the place to Norris, why would they have punished Norris and not Max...?
That makes zero sense.
personally i think the apex argument is very relevant because it is how the rules provide a guide on who should be given more weight in the arguement of who has right to the corner, however if you penalise both drivers you have effectively negated the penalty and in this case Lando would have gained a lasting advantage over Max.
