Angus is right. This is the key difference between a flow that uses "app/plan create" and one that just does "assembly create" and passes in a plan file by value.

The main idea of a plan resource is so you have an in-system reference of the deployment plan so you can easily reference it (like a template) to create an arbitrary number of matching assemblies from it. It's also a convenient place to hang initialization requirements that need to be met before you start generating assemblies, like the creation of a git repo.
