" The replica sent to Server 4 will have a hint in its metadata that suggests which node was the intended recipient of the replica (in this case, Server 1)"

Will the data get copied to server 2 and server 3 later from server 4? If server 1 is not reachable, why can't it write to server 2 instead of server 4?

Great question, I am wondering the same, did you find an answer ?

Since server-2 and server-3 are available, the data will be copied to them right away. Only server-1's data is copied to server-4 (hinted handoff), and when server-1 comes back online, server-4 transfers the data to it.
