Bored rich people playing games to get attention and yet remain anonymous? I do not know. If I had billions of dollars I would send everyone on Bitcointalk a nice number of Bitcoin.
It is possible that they messed up and were trying to actually send the 0.00525500
BTC amount to that address which is about 90 bucks but they set that amount to the change and the change (4
BTC) to Genesis address which already contains 22.57
BTC!
P.S. coins sent there are not burnt though, Satoshi may some day decide to spend them

If Satoshi is even alive still. ...

That is a bit of a horrible thought, is it not? Satoshi dies without anyone ever knowing who he was in the end.
