Starting motor free spinning

CBX 1000Z. HI all I have a question relating to my starting motor free spinning. Should the starting motor free spin while the engine is running.
When I say free spin I mean the engine is spinning the starter motor through inertia. The starter clutch is working correctly as I can hold the armature of the starter still with the engine turning. But once I release it, it will spin up to match engine speed. I can only surmise this would not be good for the starter. At a minimum it would cause excessive wear on the brushes and at high rpm the risk of bearing failure.
