Air hybrid engine

I ran across this and thought it was a cool:

From what I can see you use same number of cylinders, half are used for the pump side and other half are used for power. You get the same power strokes per revolution because it is a 2 cycle system.

From what I gather, half the cylinders are simply compressors. It's painfully similar to using a supercharger...pressurizing the incoming air/fuel charge before it's fired. I don't see a huge advantage or any groundbreaking engineering here. Frankly, I'd prefer to use all the power strokes I can get in every cylinder, and use a supercharger if pressurized intake charge is the goal.
