I think it's the next step he should be aiming for if he wants to add a bit of style to his letters. It's not hard, it just takes a bit of tweaking and a bit of practice to understand what kind of curves and what kind of angles look right.
Instead of keeping everthing square, try and angle stuff a little. Instead of ending bars in a square, try and cut them off a little into a point. Don't go crazy, just make tiny little subtle changes, it can change the look of your letters dramatically.
