Usually it's a portion difference, not a disagreement. This page scores spaghetti at a serving of 1 cup cooked (about 145g); at 2 cups or more cooked 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.
