I agree with the structure the author is putting out there and have been using it myself. It was honestly a mystery whey people would use this hard to read nested structure when you can write things in a more readable way. The best theory I can come up with is that it is easier to write that way if, for instance, you are answering a question on StackOverflow, and these examples just find their way into production code via copy/paste without people understanding how they work.
