I think Sue's right. It's two different blooms. The cherry-red one has twice as many petals as the true-red one.
Steve, I think that effect is achieved by creating a bouquet for the photograph. Some nurseries do that for their photos. They cut several blooms at the peak of perfection off various parts of the rose and stick all of them into the foliage in one spot. It's a great technique for artful shots, but it's deceptive as a marketing practice because the rose bush you buy will not produce "bouquets" of that type.
