Yes - and there’s a huge difference between the two. In a word, decentralization. By detecting unsafe material on-device / while it is being created, they can prevent it from being shared. And because this happens on individual devices, Apple doesn’t need to know what’s on people’s iCloud. So they can offer end-to-end encryption, where even the data on their servers is encrypted. Only your devices can “see” it (it’s a black box for Apple servers, gibberish - without the correct decryption key).
