I'm experiencing this problem as well. I'm running Docky 2.1.0 and OOo 3.2.0 on Lucid (2.6.32-19) and each open OOo document creates a new Docky icon.
When I have multiple OOo documents open and then close one, the OOo icon remains. If I have 10 documents open and then close 9 of them, I will still have 10 OOo icons. If I then open 10 more OOo documents, I will have 20 OOo icons.
The only way to make the OOo icons disappear is to close ALL of the OOo documents or to restart Docky.
