Wrong. Apple has decided to pretend to turn it off, but then turn it back on arbitrarily later.
Now, instead of using the more-convenient flip-up control panel, you have to root around in Settings to turn Wi-Fi and Bluetooth off. And then if you want to turn it back on, you can with the flip-up panel... but you can't turn it off again there.
Of course that doesn't make sense, but nonsense is commonplace at Apple.
