In this specific case, we want the table name to be used to qualify column names, because the target table doesn't have any alias (it's not supported by every version of every RDBMS), and not qualifying columns at all may lead to a confusing statement, in particular if tables referenced in the subquery contain columns with the same name. Since we use aliases for every other table in the query, referencing the table should not lead to any conflict.
