Yes, as is documented in DBI.
Also, your SQL seems faulty to me as the "previous record" seems to skip users:
create table users ( user_id integer not null primary key, name varcha
+r(16) );
insert into users values (1,'Fred');
insert into users values (2,'Barney');
insert into users values (3,'Wilma');
insert into users values (4,'Betty');
insert into users values (5,'Pebbles');
SELECT *
FROM users
WHERE user_id < (SELECT MAX(user_id)
FROM users WHERE user_id < 4)
ORDER BY user_id DESC LIMIT 1
(SQL fiddle)
This suggests that the "previous" entry for "Betty" (user id 4) is "Barney" (user id 2), and not user id 3 as I would expect.
The same, but inverse holds for the other SQL.
