Not how I see it. As I said, the GM stands in for reality. The Players (through their PCs) stand in for real people. So in a traditional game, the mystery is created outside the purview of the Players just like how in real life the mystery is created outside the purview of the real people investigating it. In BB, the mystery's answer is created through a process during active play at least partially under the Player's control, and which did not exist until that creation process.
Again, how are both those styles equally far from solving a real mystery?
