   # File lib/neo4j/core/query.rb

10   # TODO: Discuss whether it's necessary to call `break` on the query or if this should be left to the user.
11   Neo4j::ActiveNode::Query::QueryProxy.new(model, nil, node: var, optional: optional, starting_query: self, chain_level: @proxy_chain_level)

Calls proxy_as with ‘optional` set true. This doesn’t offer anything different from calling ‘proxy_as` directly but it may be more readable.
