Usually it's a portion difference, not a disagreement. This page scores whey protein concentrate at a serving of small scoop (20 g); at 2 scoops (40 g+) it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
