So the Joey itself has no tuners but enables use of one of the Hopper Duo's 2 tuners by a 2nd user in HD? I would thusly allege that calling that Hopper, by itself, a Duo could be misleading. A combo of Hopper Duo plus Joey could be unitarily considered a Duo system. To me, as I've previously opined, that's a step backward from being able to support 2 users out of a single box- I was actually expecting them to progress to like 4 users (Quattro?) or essentially whole home/1unit. But I suppose having both Duo users in HD is still something of a plus.
