That's likely reference to Combo 1 and Combo 2 in CCS.
CCS Combo 1 and J1772 support single phase (i.e., North American) AC power. CCS Combo 1 is J1772 plus two large DC pins.
In Europe they use multi-phase power and so they don't have J1772, instead they use a connector colloquially called Mennekes. Thus they use CCS Combo 2 which is a Mennekes connector plus two large DC pins.
In order for Europe and US to adopt the same connector, the US would likely have to switch to Mennekes because I believe it can support single, two, or three phase AC.
Or more likely this would require the US to adopt CCS Combo 1. But I fail to see how that would benefit manufacturers because they'd still be supporting two CCS connectors.
How common is actual three phase charging in Europe?
Most larger buildings in the US (condominium complexes, commercial buildings, and things like supercharger stations) have three-phase supply. But most non-huge loads get only one or two of the phases, presumably because the benefit of wiring up all three is pretty small compared to the added expense of installing an extra wire and keeping track of which phase is which.
That's exactly my point. It's far easier to adopt NACS as the North American standard than J1772, CCS Combo 1 or anything else. It requires the least change.
