The payload is encrypted not the destination IP. Otherwise how would routers be able to route the packet? What they're saying is that Warp+ will send the packet across their private network rather than sending just on the plain internet. For example: You're in Italy. You want to send a packet to a server in New York. On the internet the path is unpredictable. Because there's a lot of hops from different networks etc. Cloudfare are saying that your packet will enter their Italy PoP. (they may have more on the country I don't know) Then via their separate private network, it will travel to the New York PoP. Then out to the internet to the destination.
