Correction, I seem to have misunderstood Statis'  set up. If you really
create a new world and then create and kill the person there then the
probability of survival is 1. This is different from quantum mechanical
branch splitting.

To see this, consider first what would have happened had the person not been
killed. Then his measure would have doubled. But because he is killed in one
of the two copies of Earth, his measure stays the same. In a quantum suicide
experiment his measure would be reduced by a factor two.
  
To say that measure is doubled or halved it is not sufficient to take the measure at the final point. You really must compare measure at two points, in effect take a ratio. So depending where the initial point is you could come to different conclusions. If your initial point is before the new world is created (and the clone in that world is killed), then, you are right. There is no change in the measure of the original person. However, if the initial point is taken after the world is created but before the clone is killed, then the measure of the clone goes to zero "in that world." One could always argue that the world branches and the clone continues living in other worlds.
