I haven't finished reading this thread, but.....
There are many known near Earth asteroids (NEA's) that are dual objects, two 
asteroids orbiting a mutual center of mass.

The NEA, Hermes, is one such object.  If such an asteroid makes a close pass at 
Jupiter, the planet's gravity can separate the two objects and they would 
travel in a mutual orbit around the Sun, albeit no longer gravitationally

A separation distance of a hundred thousand KM could account for multiple hits. 
 There are "crater chains" seen on the Moon, on the Martian moon, Phobos, and 
on Mercury, that may be due to collision with a "train" of asteroids.
