From what I see, the guy is literally gathering a statistical data, hoping that maybe there is something about this curve that would make the balls more likely to end up in a certain places on the earth.
It might be a dead end, but you cannot blame him for trying. I personally appreciate it.

What Do I Actually See Here?
We are generating random Bitcoin addresses, that match (in the least significant 32 bits) a few of our rendezvous points on the elliptic curve (read more). Bitcoin addresses themselves are just points on this very elliptic curve. Now if the distribution of BTC addresses is completely random, we should experience a totally balanced distribution of hit rendezvous points (The bar-chart on the right hand side shows these rendezvous points and their distribution).

Time will tell, how random BTC addresses actually are. If the right "point cloud" evolves to a straight blue line, our BTC adresses should be safe. Hence if it doesn't, this will open new topics to be discussed.
