Once they hit the atmosphere, their lateral motion (groundspeed) is probably greatly reduced by air resistance, while theory downward motion is maintained by gravity. So shortly after reentry, they probably mostly stop diverging. Still, though, I feel like I would be hard-pressed to throw two objects from space and have them land within sight of each other.
