Automatically gets dropped when out-of-scope/function returns (at least I hope so)
The mutex dropping is moved to after the if condition, to allow the code to set the current_player_info.last_update value. If it was before, then it wouldn't be able to

Yes, the lock is automatically dropped & released when the return statement is hit.
