Misleading phrasing in lesson

The lesson states: "You will never use autres on its own," which in the context of the entire lesson appears to mean you would need des or d', since no other option is given for the plural, but you could in fact say, for instance, "ces autres journaux." Even if you want to make the argument that using ces fulfils the point quoted statement as to autres not being alone, it is still misleading at best.
