Yeah, that might be a bit confusing, but having extra rolls at reverse-foil cards is a good thing, because with expansion sets consistently hovering near or above the 200-card standard set mark (there are 258 total cards in this set if you count the secret rares) , it can become overwhelming to try to collect the reverse-foil versions of all of the cards they are available for, so the extra reverse-foil card should help make that easier
