Because your healthcheck will flip it back to 0 or even remove it within 
a few seconds if it's down ?

The healthcheck does nothing more ipvs wise than setting the weight with 
ipvsadm -w .....
Think about it as 2 separate processes. ipvs doesn't care if the RS is 
"up" or "down", and keepalived (or other) doesn't really care if IPVS is 
passing traffic to it.
