You may be right that I'm reading too much into it, but I'm not convinced. If the company means to say it has no control over the journal's decision on a publication date, it should say so. Instead, it has said that it has no control over the peer-review process; but once the article has been accepted, it's past the peer-review process, and it makes no sense to refer to it.
(I don't have these problems with Sarepta's communications, which I've read a decent amount of. I've read fewer of those from Annovis, but they have struck me as straightforward, too, and I haven't found them ambiguous either. I think if either of them meant to announce it had filed an LOI, they'd say as much and I'd know it; if they wanted to say an article had been accepted for publication but they don't know when it will be published, I expect they'd say it unambiguously.)
