Revisions are for the entire repository, not specific folders. When you
commit something, the revision of the entire repository is bumped up by
one. For unaffected paths, it just so happens that there is no difference
between those revisions, but those paths do have a representation for each
revision. This is explained well in the book:

I have a blog entry that is also somewhat relevant to this and might help
understand it:
