In this case, the reference repository has some useful loose objects, but not all useful objects, and we make sure that we can find the objects we fetch from the repository we're cloning in the new repository, instead of potentially being distracted by the reference repository. Doing the wrong thing in a builtin-clone implementation would lead to this looking for an object in the wrong place, not finding it (because it's only in the right place), and crashing.
