It can't be, they're both obtaining their data from the same place (the cib).

Was it running there to begin with?
Answering my own question... yes. It was:
> Jan 21 13:46:41 node5 crmd[8695]: warning: status_from_rc: Action 6
> (res1_monitor_0) on node6 failed (target: 7 vs. rc: 0): Error
and then we try to stop it:

> 7: stop res1_stop_0 on node6
So you are correct that something is wrong, but it isn't pacemaker.
