When the document has more than one title, it makes sense to use the most informative one.
The submitted title was "DO Not mention Hemisphere in any official reports or court documents". That broke the guidelines, certainly by being baity and arguably by editorializing as well.
I know, but picking an arbitrary sentence to emphasize one tendentious point is a form of spin, and thus arguably editorializing.
In the absence of any good title, subtitle, or caption, it's ok to pick the sentence from the article that best and most neutrally represents it as a whole. But that is not the same thing.
