When Jo pulls out the body of the female cosmonaut who hit the ISS, it immediately shoots off into space as if it's resuming the orbit it was originally on when it hit the station. This would not happen as the ISS absorbed all the cosmonaut's momentum when she hit it, it was absorbing that momentum that caused the damage. Now the cosmonaut's body is at complete rest compared to the station. It would not fly off into space unless something exerted some new force on it.
