I think it's the other way round, unless there has been a recent change of plan.
The centre runway would be the only one that can't operate in mixed-mode, for safety reasons (because of the missed approach procedure).
The plan is that, at any given time, one of the two outer runways would be used in mixed-mode, with the other two used in segregated mode - one handling arrivals and the other departures.
