2-way sync question.

Hello,
I understand that Hazel does not perform 2-way syncing. I have been syncing a folder on my mac to a dropbox folder. My question is what happens to a file that was added to the folder on the dropbox side when hazel's sync rules are applied? If the file is not in the folder on the mac, is it then deleted from dropbox by Hazel?
Thank you for the clarification.
