I hadn't seen one either until I ran across that one. And yeah, it does look strange.
However, I don't see why the missing teeth would be a major problem, other than maybe making the sprocket wear out a bit faster (fewer teeth engaging per rotation). I understand 1/2" pitch chain works acceptably on skip-tooth (e.g., 1" pitch) chainrings. All one missing tooth does is create a short a skip-tooth segment in 4 places on the sprocket.
