Its not a reboot because it does recon history, it just restores lost elements. Post Sundering people will remember the Spellplague, thier will still be the graves and many of scars, it won't be like it never happened, more like the healing has began, old wounds close, old burns stop burning, amputated limbs get reattached, while tumors get removed, but the scars remain.
Examples most spellplague lands might be extinguished by AO, but that doesn't mean all the spellscarred are healed or that all those who died are alive (exceptions for particular resurrected individuals).
Tymather may be returned to Abier, but a Tymather family of Dragonborn merchants that moved to Waterdeep aren't going to go with it, they'd be part of a lost Dragonborn dispora.
By the same token a restored Mulhorand and Uther isn't going be unscathed. Who knows what kind of Empire Mulhorand forged in Abier when surrounded by Godless empires. They may have a history of fighting primordials or dragons or who knows what and that will be part of thier history too.
Gods will be resurrected, but that doesn't mean that they don't remember dying or being exiled or demoted and that will leave its own scars and effect relationships. Don't expect Tyr and Helm to be BFFs anymore. If they bring back the Drow Gods, expect things,to be weird between Lolth's daughter and son having merged with each other in the past and then died as one.
See what I mean? Think of it this way, the spell is being cured, not negated, it happened, it shaped you, but the illness has been removed leaving only scars.
