My understanding (not an engineer nor even close) is the ZF8 uses the torque converter from a stop and de facto a DCT in operation for changes after that.
There Is a clutch operating anyway.
What's interesting is the new second gen ZF8 opens the clutch during décélération to lower torque and I suppose save gas and wear.
Senna did this bit I think the going logic is most like the car in gear during deceleration
