"(Then again, it may not.)"

One of the new papers on the arXiv today has an abstract that ends with the following sentence: "The work may shed light on the possible properties of different ensembles of mixed systems."

Whenever I see a sentence like that to end an abstract, I automatically think about the implicit "(Then again, it may not.)" sentence that naturally follows as the next sentence.

Update (9/19/14): This also applies to sentences that end conclusions.
