We've now fallen into the rabbit hole of moonrunes and localization. Whether they come from our own timeline or a different one, I don't think it matters at this point. I think the simplest explanation at this point is that Turo/Sada stole the pokemon from 200 years ago from other timelines, which is why they were no longer in Area Zero. The only thing we're missing context wise is who gave Heath the original page about Stellar/Terasal/etc.
