It means the ultimate (ie, "paying") customer specified the option content, as opposed to a dealer ordering generic vehicles to sit on their lot.

A couple points:

a) All vehicles are "ordered". That is, the assembly plant does not create any option content or vehicle orders for production (unless they are buying them).

b) All vehicles are "sold" before the assembly plant will build them. Again, that could be either by a paying customer or a dealership, or internal GM division, but as soon as the build passes the "pay point" in the shipping building it's off the assembly plants books. The plant is very focused on making that happen.

c) All vehicles get a "Dealer Order Number". Even preproduction units ordered by internal disciplines, like Engineering or Marketing (or Assembly plant purchased vehicles for training) which presumably do not go through a dealer per se. The Dealer Order Number is what is tracked until the assembly plant PVI (Primary Vehicle Identifier), various build sequence numbers (body shop, trim, and general assembly/final) and VIN are established (in that order).
