You should probably be talking about this on the pacemaker list, since

The xml files are identical except that one specifies that the resources are sequential while the other does not. I thought that the resources would always be collocated, but that they would either start sequentially or not, depending on the assignment of "sequential=" in the resource_set tag.
No. You specify ordering with an ordering constraint.
Please read:

and
