This refers to the set of points. When only strict equal, only the surface points fulfil the equation. With the inequality also internal points belong to the set; it is solid. Unless you have x-ray vision this does not matter :) Mark Ruvald

The article says it can stand due to the curvature being 0 at the tips, however clearly this is also true of a rotated ellipsis or circle.
