If anything than I do believe in the worst case scenario that he might have missed some literature or made an error which no one has spotted by now.
He did miss the No Communication Theorem. He should have added in his videos in Youtube that if the success of the recordings control the output being interference or not his predictions violate the No Communication Theorem.
"The no-communication theorem states that, within the context of quantum mechanics, it is not possible to transmit classical bits of information by means of carefully prepared mixed or pure states, whether entangled or not. The theorem disallows all communication, not just faster-than-light communication, by means of shared quantum states. The theorem disallows not only the communication of whole bits, but even fractions of a bit. This is important to take note of, as there are many classical radio communications encoding techniques that can send arbitrarily small fractions of a bit across arbitrarily narrow, noisy communications channels. In particular, one may imagine that there is some ensemble that can be prepared, with small portions of the ensemble communicating a fraction of a bit; this, too, is not possible."
