What triggers refresh template on server logout?


I’m trying to figure out what triggers a refresh of the layout/template when a user is logged out by the server?
I have one template (route: /) that instantly responses when I log the user out on the server; it “resets” back to te login. An other template (route: /test) while using the same layout (with the {{currentUser}} for the login-screen!) refuses to “reset” to the login screen. What can trigger a template to react to this change, or, more importantly, what can prevent it?
