Ehhh. I disagree. To me, it looks like the author acknowledged the existence of the anime, and made a small connection to the current arc but it doesn't necessarily mean that the same events took place.

I'd say it's somewhere between K-canon and A-canon: The author acknowledged the story's existence but provided very little evidence to support its existence in the canon story.
