Well, the point is that people who write good, clean code don't need to comment their code extensively. They don't need to continuously explain why they did some horrible hack or some trivialities because their code is well structured and very easy to understand based on other good software development practices. They don't write the requirements of their functions as code comments, rather they write unit tests that document the requirements etc.
