I could not agree with you more. The man has said what he feels he can. There is no doubt that he was required to sign a non-disclosure agreement. If he violates that in any way he is no longer welcome on the show but certainly wide open to a lawsuit without a leg to stand on. He would lose a lot, not the least of which is his integrity and reputation.
He had a great time, you will enjoy the show, Mr. Schaefer has a sense of humor. That seems to be enough for most people, it certainly is for me.
