You are missing the "requires a live finger" part.
The biometric system (sensor + algorithm) used by Apple, as well as other competitive biometric vendors, detect blood flow, pulse in the finger. This is done as a mitigation against fake fingers as well as the (always presented) gory "cut off the finger" attack scenario.
