Apple is a mysterious company maybe Facebook forgot to add something to the 3.0 and asked Apple to make the update fast or maybe they submitted 3.0.1 three days after 3.0.
Facebook 3.0.1 contains only bug fixes. It was submitted to Apple on the 28th. Since its only a minor update, the review process probably did not take as long.

When submitting changes developers can expedite the release if there is a major bug. These requests usually take 24 hours to process. This allows any critical bugs to be fixed immediately.

Either the bug fixes get approved quicker or maybe the devs just submitted the .0 release and by the time it gets approved they already submitted a .0.x update.
I'm guessing that Joe just used his card of asking Apple to update the app a little quicker as Joe is probably already in contact with Apple.
Although, a developer can only send one update at a time.. So the update has to get approved before re-uploading a new update.
