I done a path to make this works, if someone wants!
Now...
CREATE TABLE a (a, b);
INSERT INTO a VALUES (0, 0);
INSERT INTO a VALUES (0, 1);
INSERT INTO a VALUES (1, 0);
INSERT INTO a VALUES (1, 1);
SELECT * FROM a WHERE a.a = :a AND a.b = ?1;
SELECT * FROM a WHERE a.a = ?1 AND a.b = :b;
Have the same behavior!
