Not necessarily. If you monitor the hands, but don't manipulate them, you have a Pure Swing in which the Pivot is Hand Controlled. On the other hand(no pun intended), if you monitor the Pivot, and rely on it to bring the hands to Impact location, you have a Pure Pivot Controlled Swing. I believe the latter will force you into an Automatic Flip Release, which requires a precise Pivot to "time the flip".
