It really doesn't.
Please explain precisely what text in that article makes you think it does.
Is it possible that you think that the use of an "@" in some of these definitions is email-address-related? It's not. It's just a shorthand form that means "this domain" as opposed to a named subdomain of "this domain".
Nothing I've read anywhere about MX records suggests they can ever contain anything that relates, in email addresses, to whatever's before the "@" sign.
The sending SMTP server only uses MX records to decide which receiving SMTP server it should attempt to deliver a domain/subdomain's email to. It's up to the latter server to decide if it will accept the email; one of the criteria it applies will be its local configuration specifying whether or not emails are only accepted for defined addresses.
