don't quote me on this....but I think I read somewhere, when you aren't accelerating, it shuts off the engine or does something eco along these lines...this could be it
New Bosch system shuts off coasting cars' engines
this might explain it? Try it in sport mode and see if it does the same...
I drive mine in eco mostly but I haven't felt it brake as such infact I just find my car is in the highest possible gear and it just glides ...infact maybe if you in sport or sport plus you may find it brake a bit as it will drop to lowest gear and that will give keep.it ready for you when you hit the accelerator.
This is just speculation maybe Wolfgang can assist ...my car has not had the brake effect as such..
What mode are you experiencing this in ?
