Game theory states that exploitability(s) is expected_utility(s, best_response(s)). I think you are perhaps confusing this with whether or not a conditional probability distribution is correctly estimated. Your point would be valid if he said that, but he went much much farther than that. He claimed exploitability and not just that but a troubling amount of exploitability. Within the last month, I've implemented a function which calculates the exploitability of a strategy. I've verified my implementation on known games which are solved, reproducing theoretical results. I'm quite confident that exploitability isn't what you seem to think it is and that in actual practice calculating exploitability with the sort of screening off your are proposing isn't as safe to do as you seem to think it is.
