It actually looks to me like a harmonic balancer on the opposite side of the engine.

I believe from the picture the clutch disk and pressure plate is placed just past the second flywheel in the conventional manor. The real difference is that 1/2 the mass of the flywheel, the part that the clutch and pressure plate bolt to is mounted to the primary flywheel via an spring and damper system.

I see this as a useful means of low RPM smoothness while driving especially for people who don't know how to drive. As far as I'm concerned for performance it's a boat anchor.
