Why's that? There's a significant chance this deal won't close. There's also a chance that the deal will close and Parag will be kept on. And even if it happens and Parag goes, I don't think there's a great business case for just putting everything in amber. Twitter's competitors are moving ahead, so just freezing things will give them extra months of lead that Twitter can ill afford no matter who's owning it. I think it's somewhere between possible and likely that Parag ran this change by Musk. Who is already on record as wanting high-level changes. So this could be just as easily read as the CEO honoring the board's acceptance and getting started early on the changes. Or it could be both: Something that both the current and future CEO saw as in the bests interest of Twitter.
