I noticed this too.
And somewhat on topic: The auto-movement goes once you hit end turn. Therefore you sometimes lose a movement point.
Say, you have a warrior and you want him to move 5 turns (on flat land). On your third turn it will move the last of the five spaces but would still have one movement left. That one is lost as you will only be able to control that unit again on the next turn. Sometimes it doens't matter much, but sometimes you could have shoot another ray of arrows, or whatever.
