The author is rather nitpicky, and in my opinion overly so. At a beginner's level, teaching students to break down problems into solvable pieces, then using functions or methods to implement each piece is a sufficient introduction to modular programming. I feel that the concepts behind writing modular programs come naturally, especially when you see them in practice when using external libraries.
