Even in that video, Alec manages to slip in numerous disingenuous arguments, such as when he held up an adapter and suggested size parity between the (larger) female socket end of a complete NACS connector and the (smaller) male plug end of a AC-only J1772 connector.
More to the point, the debate isn't about NACS versus J1772, it's about NACS versus CCS1. If you compare CCS1 to NACS, the difference is substantial. This graphic is probably showing best case for NACS and the worst case for CCS1 but the connectors shown are dimensionally accurate:
