I really think the above was meant to imply that the non disparagement agreements were merely unclear on whether they were covered by a non disclosure clause (and I would be happy to take bets on how a randomly selected reader would interpret it).
My best guess is Sam was genuinely confused on this and that there are non disparagement agreements with Anthropic that clearly are not covered by such clauses.
