In some cases this is the same server as the receive connector, but it does not need to be. It is very prominent that any server that is configured as an Internet Send Connector have both a forward (A record) and reverse (Ptr record) published in Dns, and that these records exactly match what you have entered in the Fqdn field on the normal tab of your Send Connector. If this one server is hosting both the send and receive connectors, the Mx narrative should also point to this same name.

There is no requirement that an Mx narrative point to a server in the same Dns domain as the Mx record.
