A key motivator of this pattern is identifying invalid configurations early, and in particular preventing execution if a known invalid configuration is requested (e.g. fail-fast). For example, if you delete a resource from a configuration, and it ends up being one that is depended upon by another, a "plan-execute" pattern should identify this at the start and prevent any execution from happening.
