    It can be tunnelled over TLS using openssl

      That is true (and relatively easy to do with OpenSSH's ProxyCommand) but that was not the implication of the statement that HAProxy was being used in TCP mode to direct incoming TCP sockets to the correct backend SSH server based on the hostname using any SSH client that understands the SSH protocol.
