I thought Jordan had picked Sanderson ahead of time, but i just skimmed the wiki and it looks like I misremembered. Jordan was given a terminal diagnosis so he prepared copious notes. When he passed, his widow picked Sanderson because she liked his works and because of a eulogy he wrote for Jordan.
I think that’s what happened with Wheel of Time IIRC, with Brandon Sanderson taking over.
