The file isn't changed. It is exactly the same as the file in the repo.
It just isn't the HEAD revision.

Wrong! The overlay icons only tell you about changes _you_ have made
compared with the revision you got from the repo. To find out if HEAD in
the repo is any different you have to update, or just check for
modifications (click the 'check repository' button).

Well that is exactly the same situation you get without doing anything
funny with old revs. If someone else commits a broken change to the
repo, you will not see it until you update your working copy.

This is exactly the bahaviour of SVN. If it were to look in the repo for
changes, how often should it look? What if you are on a dialup line?
Will it dial up to check every time you browse a different folder in
Explorer? The WC is a sandbox. It doesn't change until you ask it to. If
you want to see what has changed remotely you have to ask for that too.
