I would not buy a bike off a nob who did that sort of thing.
He's had the bars turned to reduce the bike width for storage in a passageway or somewhere, and hasn't bothered to finish putting them straight for the photo.
If you just turn the stem on the steerer, the bike width is stem length plus bar/brake lever forwards projection. If you also twist the bars in the stem, the bar/brake lever projection is up/down and the bike is that much narrower.
