The reach start from "all around" the attacker's square. Radius is measured from a same point. In the reach diagram, it makes perfectly sense that the attacker could hit the creature on the corner squares. It could at least affect 50% of the square in the corner, so it's enough to reach anyone there. In the radius diagram, the 'logical' 10ft. radius circle is really a little wider than that.
