Because when it reaches its destination and comes out of the warp the gravity that was holding it in place is no longer there and so whatever momentum it had whilst orbiting the planet needs to be counteracted to stop the ship from moving...

But that's a tiny proportion of the total change in momentum (as viewed from an outside observer). In any case, suppose it returns to its original velocity, relative to some FoR, to keep it simple.
