I emailed one of the report authors and he pointed out the basis of my misunderstanding.The drop-off in performance was for the "scale out *in a box*" scenario where multiple Nutch instances are run on a single machine and memory usage was the issue.

Have you noticed the nose-dive on figure 11 for the Scale-out option at around 1000GB? It seems to be heading south of the scale-up figures. I notice they omit this measurement for the scale-out solution in figure 15 too. They don't seem to offer an explanation for this. Interesting paper.
