The auto-correlation feature of :func:`.select`, and
by proxy that of :class:`.orm.Query`, will not
take effect for a SELECT statement that is being
rendered directly in the FROM list of the enclosing
SELECT. Correlation in SQL only applies to column
expressions such as those in the WHERE, ORDER BY,
columns clause. [ticket:2595]
