Or it simply tells you that you have to deactivate it online on the original box first before it can be installed on another one.
I posted this before, but since people still seem to be having such a lengthy conversation about it, I'll post it again:
Also, when you put a new game into the One, the game is automatically installed on your hard drive, meaning that you don’t have to keep inserting the disc when you want to play. This sounds nice, but there’s one catch: If you want to install the game on another Xbox One—that is, if you sell your game—you’ll have to pay a fee to do so, as Microsoft told Wired in a statement. (The company didn’t specify the fee, and it didn’t say whether you could play the used game from the disc without “installing” it to the One’s hard drive.) On the other hand, Microsoft did quash rumors that the One would need a constant connection to the Internet—you can play single-player games without connecting, it says.

So it would seem that 1) you don't need an internet connection to play single player games and 2) once a game is installed it is linked to that particular machine and if you want to use it on another machine there will be an unspecified fee to do so.
This should take care of both the always on-line rumor mill as well as the used games hub-bub.
But, I'm sure it won't.
