The more likely alternative is that Harry Potter is hugely popular and referenced so many times in so many places that whatever training they did ended up weighting it more heavily. Possibly also people mimicked the author's style and linguistic patterns so much that it is easy to reproduce.
Although I personally liked Sandman Slim, given the subject matter of that book, it didn't have anywhere near the widespread cultural impact.
