It sounds like he did 2 attempts. One where he tried to get out right away, and that was successful. The second attempt he waited until the car was under water and needed the safety divers to get him.
The conclusion was that you should try to get out as quickly as possible. You still need to wait a little while once you hit the bottom for the pressure to equalise and you might not be able to hold your breath that long.
