You're pointing out the same thing I was wondering about when I read 
about this kickstart mechanism: We don't want to configure password 
policies in two places - thats only going to lead to anaconda 
disagreeing with the installed system.

I think the difference of opinion is only about the enforcement part. 
If pwquality gives us useful information about that quality of the 
password then we absolutely show that to the user and help her to come 
up with a better password.
