I would agree that it's a badly worded sentence. What they mean is that additional duplications of the tripeptide repeat also happened after the proto-ORF had ackquired transcriptional regulation. That's why the dark blue part in the figure become significantly longer in the last step F, as they write in the figure legend: "(F) Intragenic (Thr-Ala-Ala)n cds amplification, fulfilling the antifreeze function under natural selection."
Actually, there were 3 duplication events claimed by the authors. Look again at the figure.
Yes, and the one under selection is the last one. Obviously.
