I suggested an explanation that apparently was lost in the discussion.
Suppose each asteroid has a swarm of smaller rocks in orbit around
it. Suppose one of these rocks was in an orbit that caused it to
approach the earth from the opposite direction at the time of the
meteor strike in Russia. Overlooked in this discussion was at least
one other large meteor reported near Cuba, which could have been part
of the same swarm. This is important because any close encounter with
an asteroid might result in the earth being bombarded by large rocks
coming from directions different from the path of the asteroid as the
asteroid gets close. This makes protection that much more difficult.

I would point out:
1. The event did occur.
2. A causal connection between the two objects seems exceedingly
unlikely, since they came from different directions at different
times. No one has suggested how there could be a connection, as far
as I know.
3. Therefore it is coincidence, no matter how unlikely that may seem.
