So, isn't this a rather longwinded way to say that a signature only extends to the scope of the message it contains?
It doesn't matter if I sign the word "yes", if you don't know what question is being asked. The signature needs to included the necessary context for the signature to be meaningful.
Lots of ways of doing that, and you definitely need to be thoughtful about redundant data and storage overhead, but the concept isn't tricky.
