Each VAO, and shader for that matter, has a separate space of attribute locations. It's perfectly fine to have multiple shaders use the same attribute locations. Indeed, it's a good idea to do so if those attributes conceptually mean the same thing to both shaders. A VAO can be used with a shader if that VAO's attribute locations …
