Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores popcorn at a serving of about 7 cups popped (40 g); at more than 12 cups popped 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.
