Not so true anymore depending on the version you are running:

Beginning with MySQL 4.1.2, you have more flexible control over when a
+utomatic TIMESTAMP initialization and updating occur and which column
+ should have those behaviors:


You can assign the current timestamp as the default value and the auto
+-update value, as before. But now it is possible to have just one aut
+omatic behavior or the other, or neither of them.
You can specify which TIMESTAMP column to automatically initialize or 
+update to the current date and time. This no longer need be the first
+ TIMESTAMP column.


The following discussion describes the revised syntax and behavior. No
+te that this information applies only to TIMESTAMP columns for tables
+ not created with MAXDB mode enabled. As noted earlier in this sectio
+n, MAXDB mode causes columns to be created as DATETIME columns.
