Known issues point no. 3 whmcs-multisite-provisioning

Can you explain to me more clearly this point no. 3 == Known Issues ==
3. WHMCS generates random passwords when creating a service. If a new WordPress user is created as a result, this random password is the password for the new user. If the user already exists in WordPress WHMCS still generates a random password but it does NOT change the WordPress password.
WHMCS can change the password on WordPress but WordPress password changes will not be feed back to WHMCS.

I am trying to understand the point but eventhough I read several times still not get it. Paragraph 1 said does NOT change but Paragraph 2 said can change. Do I misunderstand the wording?
