Well, I guess that would be open to interpretation - I don't get from the sentence that the "very specific circumstances" refer exclusively to the paragraphs above. Otherwise, they would have written "outside the circumstances mentioned above" or omitted the brackets entirely, IMO. I believe they phrased it this way so some discretion can be exercised if the original title doesn't give the full context. Another example is the recent Tesla story - original title is "Q3 2019 Update", story title is "Tesla Q3 Financial Results". The HN story for when MS bought GitHub is "Microsoft acquires GitHub", while original title was "Microsoft + GitHub = Empowering Developers". If there wasn't such a leeway, most acquisition stories would be titled "Our incredible journey".
