It's looks like top-to-bottom style of development: first, algorithm is written in text, then implemented in code. Kind of literate programming. Sometimes it helps, sometimes it not. Usually, this style is used right after the school, by inexperienced programmers incapable to keep algorithm in the head in parallel to development, or when experienced developer does his first steps in a new language. Not a problem for me. Usually, I clear them out.
