I also think that was it, though the original config does not do that.

You can do even simpler by not specifying ports then :
Listen mybackendLB
bind 10.6.200.14:443
bind 10.6.200.14:555
bind 10.6.200.14:8009
mode tcp
balance roundrobin
option httpchk "/test.html"
server app1 192.168.0.20 check port 8008
server app2 192.168.0.21 check port 8008
Then haproxy will connect to the server on the same port it received
the connection on. It's rarely used but for such things it can be handy.
