You've given this a lot of thought. Check out images of Bianchi Infinito CV bicycles as they use Fulcrum 5 LGs, either in image searches or on the Bianchusa.com site. While I cannot tell how they position the front hub and the "Fulcrum" label across the hub, it seems 50% of them have the orange warning label an QRCode facing the DS on the front wheel and 50% have those labels facing the NDS. All of the rear wheels have the labels facing the NDS. I'm inclined to believe that the "hand builders" don't pay any attention when the pull out a front hub and rim from the parts bin. If they were using old-style Campy hubs they would need to pay attention.
