That is the theoretical construct in the German system. However the differences are fading and to me it does not seem to be like German universities, as actors of (self-proclaimed) highest art in their topics, are doing very well. Btw: Though I enjoyed Maths much more than CS, I wouldn't have understood Linear Algebra without watching the MIT Open Courseware thingy by Gilbert Strang. I think that's saying a lot about the German art of teaching (at least at that time).
