To be charitable, I suppose they mean getting your protein from whatever falls out of this high vegetable diet naturally.
You're right though, I think vegetables have more protein than people are led to believe, especially since the health/fitness industry make it seem like you need to be ever vigilant in getting your protein numbers up. Meanwhile, the average American accidentally eats far more than they need and certainly doesn't need to resort to supplementation.
They don't have complete amino acids profiles, so most plant based protein won't stimulate mtor and igf-1 like say... Whey protein, milk or a steak would.
