Unexpected behavior after configuring HAProxy Template Router Settings

There's possible to open any quantity of multiple parallel socket connections from one IP on route's host and port 80 over configured 'rate-limit-connections.concurrent-tcp' and 'rate-limit-connections.rate-tcp' parameters.

Openshift version 3.6

Steps To Reproduce

1. Create route and configure it with the following annotations:
   haproxy.router.openshift.io/rate-limit-connections: 'true'
   haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp: '1'
   haproxy.router.openshift.io/rate-limit-connections.rate-tcp: '1'
   haproxy.router.openshift.io/rate-limit-connections.rate-http: '10'
2. Try to open multiple concurrent tcp socket connections (2 or more).
3. Ensure that configured rate-tcp and concurrent-tcp limits are are not exceeded:
   sudo lsof -i -P | grep -i "established"

Current Result

java 38615 user 29u IPv6 0x327a86683dfe73db 0t0 TCP 192.168.206.50:55799->myhost:80 (ESTABLISHED)
java 38615 user 30u IPv6 0x327a86683dfe851b 0t0 TCP 192.168.206.50:55796->myhost:80 (ESTABLISHED)
java 38615 user 31u IPv6 0x327a86683dfe685b 0t0 TCP 192.168.206.50:55798->myhost:80 (ESTABLISHED)
java 38615 user 32u IPv6 0x327a86683dfe909b 0t0 TCP 192.168.206.50:55797->myhost:80 (ESTABLISHED)

Expected Result

Concurrent connections to route are equal to '1' (concurrent-tcp=1)
Opened connections to route are equal to '1' (rate-tcp=1)

Additional Information

See full route config and utility for opening multiple concurrent connections.
