Thanks, that’s useful feedback. As you probably guessed, using the two `object` declarations was a convenient way to include both URLs in the same source file without having a name clash. But I agree that it’s a little confusing, since it means the code in the downloaded source file doesn’t exactly match what I’m describing in the book. I’ll see what I can do to improve that. Adding a note in the text, as you suggested, sounds like a simple solution.
