How is it different from the DBpedia public SPARQL endpoint?

The DBpedia foundation provides a SPARQL endpoint free of charge. Although this is fine for getting started, the public SPARQL endpoint is a shared resource which can support only queries of limited complexity and which contains only a subset of the facts in Wikipedia. Specificially:

As the Ontology2 edition is a dedicated resource, you have the ability to run queries of arbitrary complexity that may time out on the public endpoint. Overall you are likely to experience better performance and may experience better reliability as you are isolated from the actions of other users.
