Creating content for a general level would not seem important. As with many other factors I assume that there could be relevance between the vertical, keyword phrase and the "reading level".
For example, if the audience is researchers and the keyword phrase pertains to research intended for academics, the reading level should be advanced. If I were analyzing content as a search engine I'd find low reading levels for content of this type to be suspicious.
