Incorect join when Argument "Taxonomy: Term Id (with depth)" is set to depth more than 1

When I add Argument "Taxonomy: Term Id (with depth)" and set it to 2 module generate this sql:

 LEFT JOIN term_hierarchy term_hierarchy ON term_node.tid = term_hierarchy.tid
 LEFT JOIN term_hierarchy term_hierarchy_1 ON term_hierarchy.parent = term_hierarchy_1.tid
 LEFT JOIN term_hierarchy_1 term_hierarchy_1_1 ON term_hierarchy_1.parent = term_hierarchy_1_1.tid

LEFT JOIN term_hierarchy_1 at this line I get sql error
