Confirmation validation is not updated when dependant field changes

Steps to reproduce:

Go to the example page at
http://validatious.org/learn/examples/registration_html

Enter an invalid password in the password field.
Enter the same password in the confirmation field so the second validation passes.
Go back to the password field and change it to something else.
Expected: The second validation fails when you tab out of the first password field.
Actual: The second validation does not fail until you tab out of the second password field.
