TCP connections are identified by the 4-tuple of (src ip, src port, dst ip, dst port). If you look closely you'll notice that both groups represent the same TCP connections as the IP addresses and ports match up: Once as an outgoing connection from haproxy to Apache, once as an incoming connection to Apache, from haproxy.
