To me, it doesn't quite, though others should weigh in if they feel I'm off the mark. I read "can be overridden" as applying to the rest of that sentence, and the next sentence's "thus" meaning it's continuing to describe what happens when the paper size is overridden. The last sentence, referring exclusively to terminal behavior, is irrelevant to my point. Thus, by my reading, this blurb is silent on what happens in typeset output with all default settings: when the default paper size is NOT overridden and the document does not set a line length. How common this scenario is, I can't guess (since your call for -me documents went unanswered). But it seems like we agree that the blurb SHOULD document that this scenario changes the line length from what -me used in every previous groff release, and part ways only on whether the current wording DOES document that. So I welcome anyone else's reading on this. If others agree, one possible remedy would be to add this penultimate sentence: "For the default paper format of U.S. letter, this derived line length will be 6.5 inches, a departure from the package's historical 6-inch line length." (This may also entail recasting the last sentence, as this insertion makes the antecedent for "It" less clear.) Side note: the blurb misspells "overridden."
