Yes. That's only a very basic implementation. The SSL relocation server will not do client cert verification and there's no way to configure the client to use specific cert right now. I think SSL cert verification could be a way for security. But you need distribute the certs to all the servers in a pool and reload xend relocation server to use the new certificate.
