I guess the problem is that the author sounds less credible saying "minimal convex hull," because that's the only type anybody cares anything about. In the computational geometry literature the phrase "convex hull" almost always implies the minimal, unique convex hull. Using the phrase makes it sound like he googled the algorithms for half an hour and wrote up an article about it.
