BitCoin Transfer - Confusion about received transaction

Trammell initiated a new email thread about a puzzling transaction. He had sent himself 100 BTC from his work Bitcoin client to his home client using a Bitcoin address (rather than by IP), but the transaction details showed an unexpected label:

After that first transfer of 25.00, you didn’t send me another 100.00 did you? I sent myself 100.00 from my BitCoin application at work to my one at home using the BitCoin address rather than by IP. My application at home has a 100.00 transfer received, however it’s transaction details say “Received with: Satoshi 12higDjoCCNXSA95xZMWUdPvXNmkAduhWv”. That is not my BitCoin address from work, so I assume this means that I received the payment encoded with a block that was computed by your client?

Trammell didn’t recognize the Bitcoin address shown and wondered how the software knew Satoshi’s name, since he didn’t recall ever entering a name in the application. This confusion highlighted early usability issues with Bitcoin’s address book and transaction display that Satoshi would address in his reply.
