Eos will be a new blockchain when the sale is over. The first block in that chain will have a eos distribution that is equal to the snapshot of the eth tokens at the end of the sale
If you want to access the eos on the new blockchain you will need a key on the new blockchain
You use the register to declare what key you will be using on the new blockchain"
