SLES 11 SP1 updated
SLE HAE SP1 + updated
node1 hostname: 

this is a 'distributed' and/or 'Active/Active', two nodes Cluster.

Scenario:
Cluster starts resource A on node1, and resource B on node2, due to
following location constraints:

  location PrimaryLoc-of-A A +inf: node1
  location PrimaryLoc-of-B B +inf: node2


B is a resource that is dependent on resource A, therefor I have a order
constraint:

   order first_A_then_B : A  B

Now node2 blown, so cluster starts moving resource B(i.e resource 'B'
failover) on node1(where resource A is already running).. but during
this process Cluster first stops and starts(restarts) resource A, and
then starts B.

Problem/Question:

Why Cluster restarts resource 'A' during failover process of resource B
