Any interest for DT-To-Go if no docs in Database?

In order to duplicate documents, I never actually imported docs into DevonThink Database. I just make DT point to folders and index them instead. All folders are shown with the little arrow showing me it’s a shortcut, a pointer to the original folder/docs.
My guess is, that in this case, DT-To-Go is useless as synchronizing won’t sync the DB itself since it is more or less empty: no docs inside, juste indexes and meta data.
Is that right?
Thanks for any clarification.

You can view, edit, organize or rename etc. indexed files in DEVONthink To Go too.

Good thanks for your prompt reply.
