String Theory Socks by Anita Grahn question

I’m having problems understanding this pattern (and I made it before so don’t know what my problem is!). I’ve contacted the designer but haven’t received an answer yet. Under the Instep directions after Rnd 1 and Rnd 2 and charts it says Work Rnds 1-2 four more times. Am I correct in assuming I finish the charts first, or am I only doing the first eight rows of the charts? (Clearly I need more sleep.) Pattern (I don’t know how to link.)

Update: I’ve heard back from the designer.[LEFT] - the chart doesn’t get finished for size S. First 10 rows of chart are increasing every other round, the next 14 are increasing every round - so, that part is now cleared up for me.[/LEFT]
