I encourage readers to actually see what I had to say in the book by downloading the PDF before taking these arguments too seriously.
But the section you're quoting is among the most contrived examples that RBP gives, it's mainly just part of a list of the different sorts of argument processing Ruby offers and the trade-offs betweeen them.
They assume that you're already comfortable with the language, but then go back to show how that language uses CS concepts.
None of them are long reads, and there are clear take aways that make you better at programming.
We had a private mailing list for this in RBP, and it was amazingly effective.
