Maybe he was gonna saying "I'm the first person who received first bitcoin transaction from satoshi"
Is there any information who have sent Hal 1 bitcoin as "the first real transaction"?
The 1 BTC that Hal received before the 10BTC came from the same wallet that sent him the 10BTC.
The 1 BTC ended up in 15NUwyBYrZcnUgTagsm1A7M2yL2GntpuaZ (Hal's assume address because these coins were swept along with the "first 10btc Hal received from Sat" and the 1btc came from 13HtsYzne8xVPdGDnmJX8gHgBZerAfJGEf (assumed Satoshi Change Address) which came from 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S (Assumed Satoshi Main Address)
The 10 BTC came directly from from 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S.
