Agree and Im not talking politics but after the last two fda approvals no one doubts that they were politically motivated...so while in theory the thought that there could be a mutual announcement, such a deliberate decision for the sake of the credibility of the drug, etc now would be counter to all of fda's actions up to now.
If anything I would think it may be more plausible that FDA got wind of the looming approval and is strong arming UK to claim this is their find and they will announce first.
(btw, these hypotheses are fun to think of when the fact may be, the meeting was rescheduled for Friday, lol)
