They're just there, as I speculated, to avoid slowing down the character advancement for people who play the DLC before the end.

I do hope our stats transfer over as fully as possible though, I'm sitting on a Shepard with all the upgrades he can get. Only missing some for the Shotgun, which I don't use. Would be a shame to lose that.
