Could it be this?
From what I read, I took it to mean that in this row, you will be dividing the front of the sweater - making the V.
That is why you need the two balls of yarn. One will go right, the other left. The should happen when you are on Row 9 of the pattern. (which is Row 5 repeated, but hey...who's counting!)
You are now done doing the full cable pattern.
Hope this helps.
