Dynamic Active/Active/Standby Load Balancing

Is it possible to monitor multiple nodes using a reverse monitor?e.g.

i assume 200.200.200.101, .102 and .111 are server1, 3 and 6 respectively. anyway, the problem i found is this does not work when server is shutted down (i.e. port 80 is not listening). i am not sure if it is expected (actually, i think it is not).

[root@ve10:Active] config  b pool foo list
pool foo {
   monitor all myhttp
   members {
      200.200.200.101:80 {}
      200.200.200.102:80 {}
      200.200.200.111:80 {
         monitor monitor101 and monitor102
      }
   }
}
[root@ve10:Active] config  b monitor myhttp list
monitor myhttp {
   defaults from http
   interval 1
   timeout 4
   recv "UP"
   send "GET /status.html HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n"
}
[root@ve10:Active] config  b monitor monitor101 list
monitor monitor101 {
   defaults from http
   interval 1
   timeout 4
   dest 200.200.200.101:80
   reverse
   recv "UP"
   send "GET /status.html HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n"
}
[root@ve10:Active] config  b monitor monitor102 list
monitor monitor102 {
   defaults from http
   interval 1
   timeout 4
   dest 200.200.200.102:80
   reverse
   recv "UP"
   send "GET /status.html HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n"
}

 when .101 and .102 return "UP"

[root@ve10:Active] config  curl http://200.200.200.101/status.html
UP
[root@ve10:Active] config  curl http://200.200.200.102/status.html
UP
[root@ve10:Active] config  b pool foo|grep -i pool\ member
+-> POOL MEMBER foo/200.200.200.101:80   active,up
+-> POOL MEMBER foo/200.200.200.102:80   active,up
+-> POOL MEMBER foo/200.200.200.111:80   inactive,down

 when .101 and .102 do not return "UP" (i.e. they return "DOWN")

[root@ve10:Active] config  curl http://200.200.200.101/status.html
DOWN
[root@ve10:Active] config  curl http://200.200.200.102/status.html
DOWN
[root@ve10:Active] config  b pool foo|grep -i pool\ member
+-> POOL MEMBER foo/200.200.200.101:80   inactive,down
+-> POOL MEMBER foo/200.200.200.102:80   inactive,down
+-> POOL MEMBER foo/200.200.200.111:80   active,up
