[Pacemaker] Removed nodes showing back in status

I have a 5 node cluster (but it could be any number of nodes, 3 or larger).
I am testing some scripts for node removal.
I remove a node from the cluster and everything looks correct from crm
status standpoint.
When I remove a second node, the first node that was removed now shows back
in the crm status as off-line.  I'm following the guidelines provided
in Pacemaker Explained docs.
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/s-node-delete.html

I believe this is a bug but want to put it out to the list to be sure.
Versions.
RHEL5.7 x86_64
corosync-1.4.2
openais-1.1.3
pacemaker-1.1.5
