bad logon attempts against the Unlock dialog box don't count

Hi all,
I have a quite weird question to ask about the lock user lockout account threshold. We have found in the Windows NT, 2K and XP documentation at the Technet; and also at the msdn websites, this note:
"Note: Bad logon attempts to a workstation against a password-protected screen saver don't increase the lockout threshold. Similarly, if you lock a server or workstation using Ctrl+Alt+Delete, bad logon attempts against the Unlock dialog box don't count."
...but, oh surprise!, we have tested this against three diferent domains (including an old WNT), and the behaviour is exactly the oposite, all failed password attempts count as failed logon. In my opinion this is the correct way to do the unlocking of a workstation, because if not, it would be a higly security risk for the users passwords, obiously. The curious thing is that we have found the above note in several places, but we are not capable of reproduce that behaviour. In all of our tests we allways get the user acount locked.
Do you know if this is a documentation "mistake"?
If don't, does someone know how to configure the AD or users workstations, to achieve the behaviour the above note says?

The note above is at the Technet here (for XP): http://www.microsoft.com/technet/prodtechnol/windows2000serv/deploy/confeat/08w2kada.mspx
The msdn note is here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gp/507.asp

Thankyou very much.
