Why isnt Tom Hanks returned in this cypher query?

Question

When running this from the Neo4j movie intro

MATCH (tom:Person {name:\"Tom Hanks\"})-[:ACTED_IN]->(m)<-[:ACTED_IN]-(coActors) RETURN coActors.name
<         


        

Answer 1

Relationships that are matched multiple times in a single pattern will not be included. (tom)-[:ACTED_IN]->(m) on the left matches the ACTED_IN relationship from Tom Hanks to the movie. This relationship will not be matched again on the right hand side.

Some more examples of this in the Neo4j Manual- http://neo4j.com/docs/stable/cypherdoc-uniqueness.html
