I think it should help in a way. But I also believe that people overestimate how well one can learn in depth about a complex problem from reading or any mainly passive activity alone.

I know there is this theory about learning styles but it's largely debunked.

To get a really solid understanding of a topic such as a business domain and it's interaction with a complex process and application, it takes a certain amount of time and contact with real problems. The only time that people can quickly pick up new ideas from reading is when they have mastered all of the underlying concepts of that knowledge. But applications generally have layers of very specific knowledge required to understand the problem and existing solution.

The point of the article I think is that it's usually going to take a significant amount of time for new developers to become familiar, regardless of how good the source or documentation is.
