For every routed signal, we have to ensure that we have a proper return path that is located where we want it and that we don't obstruct already created paths, because signals sharing a part of the return path have common impedance coupling (energy coupled from one signal to the other).
We need to establish where the path is and that it is not shared for two sensitive signals to avoid common impedance coupling between them.
