You don't seem to give Satoshi himself much credit. He surely would have recognized the significance of slipping in the 1MB block size and commented on the commit if he felt like discussing it.
Nope. He made lots of changes and didn't comment on them.
I actually don't think I was around when Satoshi put the 1mb limit in place. I played with Bitcoin back in early 2009 but nobody used it so I lost interest and came back later. Back then he routinely made big or hard forking changes to the protocol in giant commits that mixed many changes together and had no useful descriptions. It was still his personal toy/prototype thing, so he got away with things we wouldn't be able to do today.
I'd say he likely had something deeper in mind. But unlike our friends above, I don't pretend that my mind reading abilities are strong enough to overcome the space-time continuum.
