I decided to test this update a bit, and it doesn't appear to work correctly with Tradeback moves. Going off the second part of the screenshot, it's not an error for whether Pokemon don't learn moves at all, it's specifically tradebacks.

Ninetales absolutely does learn Hypnosis via Tradebacks, as evidenced
here. This happens with any tradeback move; one example that shows this is a false negative for all of them is Surf Tauros, which can be learned at any point after transfer to Gen 2, as it's learned via HM. There is no logical reason as to why they "can't be transferred".
What should be said is something akin to this, like "Transfer from Gen 2 to 1";
