My Domain - SAML SSO Login Page

We are preparing to deploy My Domain in our org, but wanted to confirm the following items before doing so.

1) We currently use SAML SSO / Federated SSO via ADFS. When we deploy My Domain, per this article (https://help.salesforce.com/articleView?id=000003861&language=en_US&type=1) we will be able to restrict users from logging in using the standard salesforce login (login.salesforce.com), correct? I'm finding contradictory information, though. Per this article (https://help.salesforce.com/articleView?id=faq_domain_name_sso.htm&type=5), it states that "the Salesforce SAML endpoint (login.salesforce.com) continues to work for SAML and OAUTH requests, even if your org deploys My Domain and selects Prevent login from login.salesforce.com in the My Domain Settings."

2) If the answer is yes to #1 and backdoor access is needed, we can use login.salesforce.com/?login or our mydomain URL of inxpo.my.salesforce.com/?login, correct?

3) If yes to #1 and #2, what will the user experience be for the mydomain customizable login page using SAML SSO / Federated SSO?
