^ Adding rebound damping slows down the fork more when it extends back out from being compressed.
BTW, it's normal to feel a bit of "top-out", obviously to a lesser extent with forks that have negative springs or chambers... but it will still be there. The combined weight of the wheel/tire/brakes/fork slider/axle has inertia and when that movement stops you will feel it, clunk or no clunk.
