It's a for credit online course that's available for cheap and as a non-degree student (i.e. MOOC). So it's the first set of courses to try and bridge the gap between MOOC's and "traditional" online courses/degrees.
edit: Although now that I think about it I should have guessed. Having a system with an expensive tuition to be paid by the student probably doesn't roll so well with pick-and-choose online courses for everyone.
