With this setting the URL of the iframe is added as parameter to the current URL. The parameter can be defined in the setting before. If this is not set the default "iframe" is used (be aware of <a href="https://codex.wordpress.org/Reserved_Terms" target="_blank">reserved words</a>!). This feature is only enabled for the remote domain if you also enable auto height for remote domains because the URL of the iframe is sent with the same request. This enables bookmarkable URLs where you go directly to the last page in the iframe. Shortcode attribute: add_iframe_url_as_param="same", add_iframe_url_as_param="false". If you use the shortcode add_iframe_url_as_param="remote", you also need to set this before ai_external.js like shown in the demo.
