pool member monitor versus pool monitor

Not sure if this behavior has changed now. When I apply node-specific monitor and NOT pool monitor, my pool remains blue. Shouldn't pool be green if each member in node-view shows each member green?

Does it mean there is one monitoring going on for each node from node-monitor perspective and another monitoring going on from pool's perspective?

Here are my definitions:

ltm pool prd-pl-vsp_mdm {
    members {
        prd-pl-vsp1:any {
            address 172.26.225.100
            priority-group 1
            session monitor-enabled
            state up
        }
        prd-pl-vsp2:any {
            address 172.26.225.101
            session monitor-enabled
            state up
        }
    }
    min-active-members 1
    monitor Server-Monitor-8443
}

ltm node prd-pl-vsp1 {
    address 172.26.225.100
    monitor Server-Monitor-8443
    session monitor-enabled
    state up
}

ltm node prd-pl-vsp2 {
    address 172.26.225.101
    monitor Server-Monitor-8443
    session monitor-enabled
    state up
}

Thanks.
