Describe the bug
Age is allowing invalid reuse of variables in MATCH clause.

How are you accessing AGE (Command line, driver, etc.)?

SELECT * FROM cypher('cypher_vle', $$ MATCH ()-[p]-()-[p *]-() RETURN p $$)as (p agtype);

ERROR:  column reference "p" is ambiguous
LINE 1: ... cypher('cypher_vle', $$ MATCH ()-[p]-()-[p *]-() RETURN p $$)as (p...

Expected behavior
Should have error out with an apropriate message e.g duplicate variable.
