That was September 24th 2016, about two weeks before citizencon. And that was not the message received and re-broadcast by the followers, because before they were saying that SQ42 would be shown there. As dsmart said on his youtube thing, SQ42 was an "on again, off again" thing.

Star Citizen Single Player SQ42 missions will be shown at Citizencon. Procedural planets with forest as well!

And here's a quote from Chris Roberts a few weeks earlier:
"We're […] taking one of the missions that's in Squadron 42 and showing how that would feel, from the briefing, to the ship, to taking off, to the mission, and the combination of flying and FPS stuff, so those are the two things we're going to show. We're going to show full-focus this is what V2 planets can do for you, then this is what Squadron 42 is going to feel like and play like, and this is the experience of a mission in SQ42...."
So yes, two weeks before Citizencon CR was starting to dial down the expectations for a SQ42 demo at Citcon. But before then, it was definitely going to show SQ42.
Also, if you're thinking that this demo is in any way shape or form representative:
For the CitizenCon demo, though, a special planet has been created for a “Homestead demo.” This planet is more Earth-like in its biome distribution, containing forests, oceans, mountains, and deserts; the Homestead demo won't see inclusion in 3.0 and is purpose-built for the CitizenCon unveil of Planets V2
