The last element of the list of forty-eight habits of Torah-acquisitive people in Avot 6:6 is, unlike the previous forty-seven, presented with a statement about its particular positive consequences:
והאומר דבר בשם אומרו, הא למדת כל האומר דבר בשם אומרו מביא גאלה לעולם, שנאמר (אסתר ב), ותאמר אסתר למלך בשם מרדכי.
... citing the source, for it is taught that one who cites a source brings redemption to the world, as it says (Esther 2:22): "Esther told the king in Mordekhai’s name."
I am a big fan of this prescription; it makes sense to me as a fundamental of intellectual honesty in all realms, including that of Torah. As such, I certainly like the idea that practicing and promoting it brings redemption. However, I don't really know what that means.
What did the Sages mean when they taught that proper citation brings redemption to the world?
Did they mean that, in an esoteric sense, proper citation hastens the Messianic Redemption (like the notion of "adding bricks to the Temple")? If so, why this linkage, in particular?
Did they mean that, like in the cited story in Esther, proper citation leads to lives being saved? If so, how does that work?
Did they mean "redemption" in some other way? If so, what, and how does proper citation lead to it?
Were they just making a hyperbolic, Biblical flourish to end the list of habits? If so, why this flourish on this element?
Answers based on sources or on your own reasoning are welcome, but I'm particularly interested in answers that make a convincing case that the explanation they present is what the Sages actually meant.
