And even if it wasn't, we're talking about a professor who never achieved his dreams. In other words, he's never met or studied a Paradoxmon, he's never completed or tested his time machine, he doesn't understand the Terastal and Terapagos phenomenon in its entirety.
So, like all scientific research, there is a ‘before’, based on hypotheses and ideas, and an ‘after’, when the answers are obtained. The AI has the memories, personality and knowledge of the real professor, but has achieved its objective. It is therefore better informed and completely up to date, compared with the person we met at the lake who has not yet realised his dream.
If these were other timelines, we'd just have said:
"it's from an alternative past/future and we've brought it back to our world".
When we were studying alternative timelines, with SM/USUM's Ultra-Brèche giving access to a timeline with a 12-hour shift, or Anabel or Rainbow Rocket's journey. We're always talking about other dimensions, other worlds.
Even the treatment of the Ultra-Beasts is different. It's made clear that they don't come from our world, like strange who never belonged. Nothing fundamentally excludes Paradoxmon from the main timeline, it's not even like Mega-Evolution which explicitly has timelines without and with Mega.
Come on, we meet Archie from another timeline, I guess he doesn't exist in any other timeline and therefore his exclusive from another timeline ???
The encounter at the lake is just a loop, as the notes from the depths attest (and even the anime confirms that it's time travel).
And in the worst case, the book exchange is just a way of breaking the loop. GF won't destroy our backup to undo the events, so it creates a new timeline from our past.
Creating a new timeline from the moment the exchange takes place (because it can be a result of time travel).
