That’s not the point they’re making at all.
The point is when a website password breeds needs to be changed, then it won’t conform to the system anymore. Now you need to make a new system, or remember this particular exception.
I had a system with a number in it. Any time a password change was needed then I would add 1 to the number. I might have to try two or the times to get the password right if I’ve changed it for the third time.
