Actually if done properly it is actually beneficial. Tranny gears normally wear on just one side under load, when down shifting, from my understanding it keeps an even wear on gears. Also the higher revs help in keeping the combustion chamber clean as during the engine deceleration the car is lean. Keep in mind if you don't rev match properly you put undo strain on the synchros as well as the clutch. Since you have a DCT the computer will make sure that the downshift will be performed correctly.
