She just got the role, why would she no longer work there? Presumably she was put there to enable this, after Yoel Roth abruptly left (and was subsequently defamed as a pedo by Elon, what's with the guy and pedophiles).
She started in June, she then quit shortly after Elon took over, then she was convinced to come back.
Musk has previously claimed his use of the word "pedo" comes from South Africa where he says it is/was a common insult when he was growing up, akin to calling someone a "creep" in American English
