Premium Pilot
It's actually been renamed "Orientation Lock" in the Pilot app.
When the switch is flipped to F, this is the screen that pops up.
By "current nose direction", they really mean the current side of the aircraft which is facing away from you. A bit confusing, as the current nose direction is actually where the real nose of the aircraft is currently pointing, which is normal flight mode, so activating Orientation Lock wouldn't change anything! Must be a Chinese translation!

There's two things going on here, the setting or resetting of the OL, and the activation/use of OL.
Initially the OL is whichever direction you're facing at warm-up/take-off.
You are facing North so this is now the Locked Orientation. i.e. Right Stick forward/Up = move North.
You begin flying and have stopped with the quad facing East.
You activate or enable (not reset) the OL.
Now when you push the Right Stick forward, or up again, the quad will move sideways or to the LEFT (North) not to the East because the Orientation Lock 'assigns' North to Right Stick forward.
IF you reset the OL in flight and REMAIN in OL flight mode then your last sentence is true but once you exit OL and the nose direction changes ACTIVATING OL reverts to the previously assigned orientation.
