[Pacemaker] Why "order o inf: VIP A B" starts VIP, A and B simultaneously ?

Hi all,
My setup is as follows : RedHat 6.3 (yes, I know,this is quite old) ,
Pacemaker 1.1.7, Corosync 1.4.1.
I noticed something that is strange because since it doesn't complies with
what I read (and understood) from the following ressources :
1. http://crmsh.nongnu.org/crm.8.html#cmdhelp_configure_order
2.
http://doc.opensuse.org/products/draft/SLE-HA/SLE-ha-guide_sd_draft/cha.ha.manual_config.html
The strange behaviour I experience is related to ordering.
Let's have this very basic case :
One zookeeper process, and one PostgreSQL master. I want them to run
alltogether on the master node. Since they bind on the VIP IP, I want the
VIP to be started before ZK and PostgreSQL.
So I setup :
primitive VIP73 ocf:heartbeat:IPaddr2 \
params ip="192.168.73.222" broadcast="192.168.73.255" nic="eth1"
cidr_netmask="24" iflabel="VIP73" \
op monitor interval="10s" timeout="20s"
primitive POSTGRESQL ocf:custom:postgresql \
params repmgr_conf="/var/lib/pgsql/repmgr/repmgr.conf"
pgctl="/usr/pgsql-9.2/bin/pg_ctl" pgdata="/opt/custom/pgdata" \
op start interval="0" timeout="90s" \
op stop interval="0" timeout="60s" \
op promote interval="0" timeout="120s" \
op monitor interval="53s" role="Master" \
op monitor interval="60s" role="Slave"
primitive ZK ocf:custom:zookeeper \
op monitor interval="5s" timeout="10s" \
op start interval="0" timeout="10s" \
op stop interval="0" timeout="10s"
ms MS_POSTGRESQL POSTGRESQL \
meta clone-max="2" target-role="Started" resource-stickiness="100"
notify="true"
I then add an ordering such as this one :
order VIP_last inf: VIP73 ZK MS_POSTGRESQL:promote
I expect the VIP to be mounted, and then ZK started, and then PostgreSQL
master to be promoted. Instead, all the resources seem to be started in
parallel.
Here comes a /var/log/messages extract, taken just after a corosync restart.
It can be seen at Jun 25 05:19:52 that VIP73 and POSTGRESQL are all started
simultaneously.
Do I have something wrong here, or something I didn't understand ?
primitive VIP73 ocf:heartbeat:IPaddr2 \
params ip="192.168.73.222" broadcast="192.168.73.255" nic="eth1"
cidr_netmask="24" iflabel="VIP73" \
op monitor interval="10s" timeout="20s"
primitive POSTGRESQL ocf:custom:postgresql \
params repmgr_conf="/var/lib/pgsql/repmgr/repmgr.conf"
pgctl="/usr/pgsql-9.2/bin/pg_ctl" pgdata="/opt/custom/pgdata" \
op start interval="0" timeout="90s" \
op stop interval="0" timeout="60s" \
op promote interval="0" timeout="120s" \
op monitor interval="53s" role="Master" \
op monitor interval="60s" role="Slave"
primitive ZK ocf:custom:zookeeper \
op monitor interval="5s" timeout="10s" \
op start interval="0" timeout="10s" \
op stop interval="0" timeout="10s"
ms MS_POSTGRESQL POSTGRESQL \
meta clone-max="2" target-role="Started" resource-stickiness="100"
notify="true"
I then add an ordering such as this one :

Thank you !
