Eh?
1) Maeve has had flashbacks with the Man in Black in them. She can't be in the old timeline. In fact, one of the clues that the William/Logan story is 30 years ago, is the fact that Maeve isn't present at the Mariposa, since she's only worked there a year.
The MiB also explicitly stated this episode that he murdered Maeve and triggered her relocation a year ago.
2) The new Clementine is not the same woman that the MiB and Teddy run into (Elon Musk's wife). We see the female host MiB/Teddy run into three times: a) in Dolores' flashback of the dance instruction during park beta this episode, b) when William arrives at the park, and c) in the present timeline, as part of Wyatt's group.
So, we see this host >30 years ago, 30 years ago, and in the present.
