I think he means the password complexity policy is only measuring length, and doesn’t distinguish between upper and lower case. Not that the case doesn’t matter in the password. Just in the policy.
Don't know about employee passwords, but for Wells Fargo the online login passwords are case insensitive. I assume this is due to some legacy system somewhere, but for their system password = PASSWORD = PaSsWoRd. One of the many reasons I no longer bank with them.
