It's more likely that the fingerprint matching is made by a hardware component that is not the main CPU. The CPU talks to it with a driver which only issues answers like "finger matched" or "finger error". The CPU has no way to read the actual fingerprint data and performs operation on it, because otherwise any jailbreak would be able to access those data, and thus any "agency" with a 0-day.
