He's not talking about the contents of the ToS. Click the back button on the page, it takes you back here. You'd expect it to take you back to the homepage of the site. If you deeplink to that page then there's no way out other than editing the URL.

The fact that the back link is broken on that very page adds yet another level of irony here though.
The original Privacy and Terms links do open in a new tab so the back button is broken on the website but works when deep linked.
That's just being lazy on a /tos or /privacy page as most of us have done in our life.
