4 stroke/2 stroke CDI inner rotor

Whats the difference between a CDI inner rotor set up for a 4 stroke and a 2 stroke. The rotor still passes the same point every crankshaft revolution whether its a 2 or 4 stroke, is it just a differnet CDI box that determines to fire every 4th stroke opposed to every stroke? I'm looking at some inner rotor stuff for CRF/XR50s for like $30 on ebay and want to buy one to mess around with. Think about it. Puch CDI for $30. I like the sound of that.
