You are. It is literally a follow up to the events of the portion of 09's backstory where Romulus got supernova'd.
I think I'm getting confused by the issue of timelines vs the (supposed) whole copyright/licensing thing.
So on the timeline side, I guess there's the prime timeline - which on the face of it is supposed to be ToS-Enterprise+Disco+Picard, and Kelvin timeline, which is the movies.
And then on the copyright side, there's (apparently), TOS-Enterprise in one 'universe' and Disco/Picard/JJ movies in another.
And the copyright issue is that for anything designed under the new license, for anything that they want to monetise in merch etc. it has to be to some degree visually different from the 'original' designs that were created under the original copyright (?) This bit seems speculated upon rather than official though. And it seems some fans are taking the alleged copyright split to justify a position that new Trek isn't 'real Trek' (which is unfortunate).
That aside, though, if the copyright thing is true, that does seem relevant for the extent to which visual design can follow from the old shows. However, seeing these first pics from Picard, I'm a bit reassured... the uniforms, while different, still seem like they could have come out of a natural evolution of the TNG/DS9/VOY designs.
(Those comm badges seem huge though :o)
edit - re. Midnight's Edge, their speculation seemed to make sense of some things, but if they've just got an axe to grind I'll be more careful about taking them too seriously.
