No, the device that sits between the client computers and the host server performs what is called Network Address Translation (NAT). It hides each client "behind" it with a single IP address that is used to represent the client network to the internet.
It can do this because when each client makes an outgoing connection, it uses a unique "return address", or port, on the NAT device. If multiple clients are behind the NAT, both making outgoing connections to the same host (and the same host service, or port, such as HTTP), each of the clients will have a different port number they will be calling from. When the server sends information back, it will send it to the shared IP address (the address of the NAT, which the world sees) but to the client port and the NAT will translate that to the private client network address of the client.
So, all the cookies make it to the right cookie jar.
