I believe what it means is you let the other team decide what to do in the in the beginning of the game and then you decide the start of the 2nd half. Usually the team that receives in the first half, kickoffs to start the second.

But that wouldn't neccesarily be the case here. Theoretically you could kickoff or receive twice. By deferring until the 2nd half you have the opportunity to get a sense of the flow of the game, weather conditions, etc. And then make your decision then.
