Mark, the Shubb has the approximate curvature of a radiused fingerboard so although you can hold down the top five strings with it, I am not sure you wouldn't be putting too much twist on it if you try to capo, say the top three strings.
I think Seed is right about why the dots are where they are.
I have always thought that, besides for decoration, the dots on the fingerboard itself are to help other musicians see where you are, whereas those little dots on the edge of the neck are the ones that really help you. I have an old cheapo guitar made in Italy which has the dots on the fingerboard, but not the ones on the edge. <kidding> That's the Italians for you, all beauty and no brains.</kidding>. My new LaPatrie has the dots on the edge but not on the fingerboard. Since it is a nylon stringed guitar, it probably means you can play with your snotty classical friends without them realizing you have those little "helper wheels". That's the Canadians for you....
