Snapping to vertices issue

When I am following along at around the 5:20-5:30 mark and i make a sphere and then try to snap it to the edge vertices of the original cube, it isn't putting the sphere right on the vertices. It seems to be snapping it to a defined distance but I can't tell what is controlling this. Same for if i set it to "closest" or "center". Any ideas?
