    No, not so obviously, because what you describe is just another
    way of going straight to your on-disk-cache or viewing the files
    in the cache settings of internet explorer.
    After all, the people see only the saved version of a page which
    was unrestricted at the time of saving.
    So, it might be a problem of confusing the users, esp. if it's your
    client: "Hey, but you said that this page cannot be seen from outsiders
    anymore, but I just need to press cancel ....", but IMO it's surely
    no security problem.
