Unfortunately I fail to see the logic of what you are doing and your example document doesn't disclose anything useful to aid understanding.

Either the document is editable, in which case the protection would appear superfluous, or only parts of it are editable, in which case marking those parts as editable, or better still using content controls (which are not limited to forms) would seem to make more sense.
If the document is intended to be reused then surely it would be better saved as a template and users create new documents from it, which would preclude the need to clear it between uses as the documents would match the template?
