The flywheel, clutch, and pressure plate are constantly in contact. However, when you depress the clutch pedal to the floor, you send brake fluid (same that you use for clutch) from the master cylinder to the clave cylinder, which in turn pushes against your clutch fork. When the fork is pushed, the transmission itself acts as a fulcrum. The clutch fork pushes the throwout bearing against the metal splines of the pressure plate, which in turn relieve pressure from the pressure plate, which in turn also relieves pressure from the clutches constant contact with the flywheel and pressure plate.
When there is less contact, then the flywheel spins independantly from the clutch and pressure plate = less rotational mass.
When the pressure plate is sandwiching the clutch inbetween the flywheel and itself, then there is more rotational mass.
