Ah, never mind, you're right:

> Apple’s method of detecting known CSAM is designed with user privacy in mind. Instead of scanning images in the cloud, the system performs on-device matching using a database of known CSAM image hashes provided by NCMEC and other child-safety organizations. Apple further transforms this database into an unreadable set of hashes, which is securely stored on users’ devices.

He is not right, though. The system used will not reveal matches to the device, only to the server and only if the threshold is reached.
