For further expansion. On overrun or when braking it's a simple blip, most of the time overshooting the required rpm then setting down (you can feel the down change by a surge of deceleration). When at a constant speed & throttle it's rev-matching.
I did drive the e90 M3 with it on around the Nurburgring a few years back and loved it. I just wondered if it was the same system on the e89 and obviously it is. My last f10 5 had paddles and sport auto box but no throttle blipping
