If you go to their spec sheet, note that they don't list GM4718M.

"Meets or exceeds the engine performance requirements" is oil companies mealy mouth way of saying "We recommend it for that use but the car manufacturer hasn't approved it"
You need to read these things like the oil companies were trying to mislead you without outright lying.
There spec sheet is interesting because it's one of very few US oils that is actually qualified for VW 505.01.
