In the case of:

        BEGIN WORK;
        SET x=1;
        bad query that aborts transaction;
        SET x=2;
        COMMIT WORK;

Only the first SET is done, so at the end, x = 1.  If all SET's were
honored, x = 2. If no SETs in an aborted transaction were honored, x
would equal whatever it was before the BEGIN WORK above.
