Yes, but less pithy. Placing the "average person" next to the "average number of legs" makes it clear that the idiomatic and intuitive sense of "average" that most people have is wrong. The more precise "typical person" doesn't make that same point as well, though an intelligent reader would certainly be expected to be able to read the same from it.
This is not general to all subjects in Danish universities. I studied physics in Denmark and while the majority of my exams after the second year match this description (though not all), my impression is that this is not at all the norm. Students in the humanities in my dorm, for example, seemed to have an overwhelming majority of several-day take-home written exams (with no associated oral defense).
