Yes exactly! The backend server is kind of like a macro or codegen system, it uses some combination of static assets and dynamic (runtime) routines to generate the assets that get shipped to the frontend. This has interesting implications in eg legal questions, like can the backend and frontend 'programs' have different licenses? If you look at them as separate programs that would seem to imply that yes they can!
