One purpose of the reference not is that you don't have to rely on indexing for getting to certain nodes. 

If you connect your nodes to the reference node in a way that puts them in certain categories you can always get to them via traversal.
Connections to the reference node are also used for visualization (e.g. for Neoclipse)

From the docs of the method:
Node getReferenceNode()
Returns the reference node, which is a "starting point" in the node space. Usually, a client attaches relationships to this node that leads into various parts of the node space. For more information about common node space organizational patterns, see the design guide at http://wiki.neo4j.org/content/Design_Guide.
