A group is essentially a shorthand for ordering+colocation, so the
ordering is always enforced.

Instead of a group, you could create just a colocation constraint,
which allows the resources to start and stop in any order (or
simultaneously), but always on the same node.

If you need them to always start in order, but stopping can be done in
any order (or simultaneously), then use a colocation constraint plus an
ordering constraint with symmetrical=false.
