Usually it's a portion difference, not a disagreement. This page scores barley at a serving of 1 tbsp cooked (about 23g); at 1/4 cup cooked or more (55g+) 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.
