No, you understand it correctly. One thing I can suggest, if you want to be
able to add variables to common blocks after they're defined, is to encapsulate
your variables into an anonymous structure. You could then redefine this
structure (as long as it's anonymous) to your heart's content.

The release notes for IDL 3.6 says that you can now nest anonymous structures.
Hurray!!!
