    yes it does
    that helps in stabilizing it.

    One of the reasons satellites are so expensive is stabilization.
    But that's orbital stabilization.

    Rotating a satellite about its axis is not neccessarily a good thing, or even needed.

    For example, an imaging satellite for weather views are best if non-rotating so that the camera(s) can stay pointed in the same direction.

    And to do that may require sophisticated stabilization, such as gyros, chemical thrusters and their required electronics.
