Doc on InnoDB AUTO_INCREMENT handling

[Steven Wong]

http://dev.mysql.com/doc/refman/5.1/en/innodb-auto-increment-handling.html says:

(1) 'Therefore, if you are using statement-based replication, you must either avoid INSERT ... ON DUPLICATE KEY UPDATE or use innodb_autoinc_lock_mode = 0 (“traditional” lock mode).'

But it also says:

(2) 'This mode [“consecutive” lock mode = 1] is safe for use with statement-based replication.'

(3) 'If you are using statement-based replication, you should set innodb_autoinc_lock_mode to 0 or 1'

It seems that (1) conflicts with (2) and (3). Either that or I misunderstand something. Would someone please clarify?
