Membership [accountform] shortcode doesn't produce payment option

Need a little clarification.

The Membership Page Options tab lists all the pages the Membership plugin creates and offers a short description of what each page does, however, the description below has be confused:

This is the page a user will be redirected to when they want to view their account or make a payment on their account.
It can be left blank to use the standard Membership interface, otherwise it can contain any content you want but should contain the [accountform] shortcode in some location.

The shortcode produces a basic profile form, as seen in the screenshot, but I don't see any sort of payment option anywhere.

Do I have to build this into the form?
