How was I "not quite true"? Because I didn't bother to specify details? Was I wrong about the reasons for the change? The comment wasn't deliberately misleading, either. There was a change to prevent direct to IP connections, as that had become viewed as a potential security risk. If the comment was wrong, that was likely accidental.
It's not quite true because you're implying there wasn't a limit. There was a blocksize limit all along, it's just that Satoshi decided it should be reduced from 32MiB to 1MB.
Look at the early commit history of Bitcoin sometime; Satoshi made really misleading comments all the time hiding major changes.
