Some people, noob or not, have a style. Some code has a style. Some programs are best expressed as narrative little stories and documenting them as such makes sense. This is often true when the program's data flow is very linear.

Some programs benefit greatly by having dense little blocks, with nothing more than a two work reminder as to what they do, that can be considered carefully and held tightly in the mind. Any program that has atomic/blocking operations or concurrency seems to fit this model.

To say that "noobs use a lot of this kind of comment" and "mature programmers use this different style" may be partly true but seems very much overly simplistic.
