Non/unique Title

So, I re-read the examples a couple of times and then I finally understood what it was getting at. In some cases, they may be giving us chapters or newsletters or something with the exact same title (ie. non-unique) so I think the person who wrote this was trying to explain what to do to differentiate. To simplify, I merged these two which I'm hoping brings more clarity. I'm happy to take direction from you if you disagree or have other suggestions.
