Regardless how it does it when you are doing say 50 in 6th and downshift to 5th, then 4th, then 3rd the road speed does not change from 50 and the rpms match 3rd at 50 mph with three presses of - button. A manual gearbox would require a throttle blip with each gear change to hold a steady speed but the DCT box doesn't. At least that is how my 2015 was.Consider an example where the DCT bike is in fourth gear and you are going to down shift, third gear on the other clutch shaft is in mesh, shift dogs engaged, ready to transmit torque when the clutch engages. If the DCT instantly disengaged the fourth gear clutch and engaged the third gear clutch there would be an engine speed mismatch. The engine has to rev-up to match road speed in the lower gear.
With out the throttle blip feature of the Africa Twin and Gold Wing, the DCT uses the clutch to pull the engine up to speed during a down shift.
The transmission pre-selects the next gear when you push the upshift or downshift button, or the software makes the decision for you if in auto.
