I want to thank you for this comment. I had read the entire article thinking incorrectly about this. I thought it was for people who didn't want to see the material to navigate away, and kept thinking "just turn your head, close your eyes, hit the back button". Then I saw your comment and realized I was entirely wrong about how I was thinking about this. I get it now.
