That's what seemed confusing to me. How obvious it is probably depends in prior knowledge here. There's absolutely nothing in a running system that needs anything from /usr/src/linux. If fact, you could, completely uninstall all kernel sources and totally wipe out /usr/src. It's only needed when you build something that needs kernel sources. Of course if you didn't know that, then yes, it's not obvious :)
