They should've put in the contract that they can't talk about duration and not even talk about that they can't talk about it.

I'm pretty sure it is in the contract, and that this is their way of telling us that the contract doesn't allow them to talk about duration, but also doesn't allow them to talk about the other details of the contract except for the part about talking about the existence of duration in the contract.
