Yes, if sneaky commander can sneak he will do so by default. If you want to make sure he moves normally and attacks a province use CTRL when clicking on province.

You can see how someone moves by arrows too. Normal arrows (reddish/brownish or whatever that color is) are for normal movement. Grey arrows are for sneaky movement.

Also, check commanders orders before hitting end turn to see if someone doing something you don't want him to do. It's good to double check if you are new to this game. Later on you will get a hang of it and these surprises will became rare.
