You want people to believe that the behavior of an antireflective
coating is, first light reflects from it, and then it's cancelled -
before anybody see's it. That's trying to have it both ways.

You're of course entitled to believe whatever you like. But you
really owe it to people to include a disclaimer when you proselytize
about it here.
