The new definition of PNB in part 2 seems to have suffered from a bit of cut & pate itus I think... for me the critical difference between PNB and PME is PNB has its N earthed at a single point (i.e. there's nothing multiple about it) - "a single source of voltage" has nothing to do with it (you can still have PV or other local generation with PNB).
