I think, depending on the work, the level of subtlety etc. one can read into and find that an author is revealing something about themselves. It's easier when they're famous and you know something about their life-story. If the only thing you know about them is their work, this is maybe harder to do.
That said, it is funny when authors are used as authorities on their work. Like when Woody Allen produces an author, who chastises the know-it-all.
The opposite, sort-of, happens when Rodney Dangerfield gets Kurt Vonnegut to write a term paper about Kurt Vonnegut and the professor he likes disparages the work.
