Perhaps it'd be better to write "... we could not have written
SELECT x, y FROM test1 GROUP BY x, because ..." ?  The first
half of the example uses "SELECT *", and this bit was meant
to be consistent with that; but if the reader is confused about
how "y" got into the discussion then writing it out explicitly
should help.
