Sounds pretty weird to me. I'm just too old to have gotten the BSc+MSc combo here in Germany (some unis had it, mine didn't) but from my experience most people here would just stay at the same university and tack on the MSc just after the BSc (this is in CS).

Oh, but for comparison my degree was officially 9 semesters (most people used 10-12), so getting "just the BSc" was a) much shorter and b) not as ingrained as the default and then going the extra mile, the combo package was more like the full replacement for the old Diploma.
