Ummm...what?
This shouldn’t really surprise anyone. I think Apple themselves acknowledged that FaceID is unlikely to be twin-proof, but of course only a small percentage of the population has to worry about that. Using a plain old passcode is still always an option.

I think what he means is that if it fails to recognize your face and then you verify your identity with a passcode, the system is designed to learn from its mistakes, so to speak, so it becomes less likely to fail to recognize you in the future.
However, I don’t see how this would help in this case. If anything, it might just get better at recognizing and accepting both faces, and make the problem worse. I don’t think there’s a way to tell the system that it shouldn’t have accepted a face.
Everything they said.
