It's interesting, but not quite a significant event, there could be many versions of the story that would lead to someone having to move bitcoins mined in 2009 and it would be be almost impossible for us to predict right. Although, it shows how far Bitcoin have come in just a number of years. At the first year of it's creation miners may have generated blocks for fun, with a free actually believing in the concept of the network. And 50BTC then meant nothing, but not satoshis are worth significant amounts.
It does not tell anything? Probably but if you think of it in more practical way, how many people just after a months of bitcoin was created would be interested to it? I doubt it would be just a random guy on the internet If these bitcoins were from the same year as bitcoin was created then most probably this is related Satoshi Nakamoto, but why they are moving this now?
It raises suspicion but it doesn't really tell anything to conclude that.
My suspicion is also this is one of the inherited btc of Hal's, @JayJuanGee might be right, it might be one of his heirs. Gonna get an update to this.
