Yes. You can't use memory node partitioning for file pages in this way unless you have strict controls over who can access the data sets in question, and are careful to prevent people from moving between containers. So it's not suitable for all uses of resource-isolating containers.
Who is to say that the pages allocated in (2) *should* be reaccounted to my_container2 after (3)? Some people might want that, other (including me) might not.
