You will notice on Kew that the stripes start out matching at the cuffs, then go awry near the ankles. I did the one on the left first and carefully pulled out the yarn to start the one on the right in the same place in the color sequence. Then, I ran into a knot! I tried to pull to the same place again, but I misjudged the blue and by the time I realized how far off I was, I was in no mood to frog so the poor dears don't match. I'm sort of ok with it, but I've developed an aversion to self-striping yarn.
