[Sherlock Holmes] Why does Watson say he's never heard of Moriarty in the Final Problem when he clearly knew enough about him to discuss his criminal activities with Sherlock in the Valley of Fear?

The adventure of the Final Problem was disclosed to the public first. Watson fictionalized a little-- either the discussion took place much earlier than the rest of the story or it was straight-up fabricated by Watson as a way to establish Moriarty to readers unaware of his crimes.
