It could conceivable just be something like a developer using the wrong draft version, the lawyer accidentally sending the wrong version after a few rounds of back-and-forths over potential drafts, or some other fairly silly mix-up like that.
Of course calling it a "mistake" is more likely to be corporate spin and back-pedalling, but you can never be quite sure because the explanation could be true, and that's kind of the point of the spin.
