Don't be silly, that was the 1980 Annual.
I'm not saying this like it's a bad thing. I think what Colfer's done is rewrite the first Doctor as if he was being made for today's tv audience, which as the stories are being aimed at the kids who watch the show today, strikes me as a sensible thing to do. There's a place for every interpretation in Doctor Who fiction, not just stories that slavishly copy the style of the tv series in any particular era. Those tales that really push the envelope can be some of the most exciting.
