The point is that offline content detection on data that will be uploaded to iCloud feels like a prelude to offline detection of all content on your device. In fact, given that Apple do not E2E encrypt backups and already implement CSAM functionality by scanning data in iCloud [1] it's not clear what the purpose of the new PSI/CSAM system is.
