Authoring a book and being an expert in the topic of said book is, surprisingly, not always correlated. I don't know this particular person, so don't read that as a comment on this particular author. I have met people whose books I have read, I have seen code written by these same people, I have talked with them about the book topic. My take away is that some people are good at writing books, some people are good at writing code, some, but definitely not all, are good at both.
