Indeed. You should keep the complexity to a reasonable level, lines of code tends to correspond to it so it makes sense to keep the number of lines of code per function low. The author doesn't understand the relationship, he blindly follows the advice to keep the number of lines low without considering the complexity and that leads to unnecessarily complex code.
