I you're re-lacing, I'd tuck under/over that final crossing as you'll get a slightly stronger/stiffer wheel. But I don't think there is anything wrong with running them the way they are. As the previous poster said, you should be able to use the same spokes if you want to re-lace. A lot of discussion on this forum about re-using spokes, but I take wheels apart for a thorough cleanup and re-lace with new spoke nipples (but old spokes and rim) quite often. Never had any issues whatsoever. I do keep track of spokes carefully in four groups so they return to the same flange (left/right) and same orientation (head-in or head-out).
