Codex:

Flushes the rewrite rules when a page or post at the random content base changes.

A published page at the random base, for example example.com/random/, takes precedence over random content redirects. So does a published post when the permalink structure places posts at the same URL, for example /%postname%/, see WP_Rewrite::post_permalinks_share_random_base. As the rewrite rules account for the page or post, they need to be regenerated when it is published, unpublished, renamed, moved or deleted. Runs on the {@see 'wp_after_insert_post'} and {@see 'after_delete_post'} actions. Third-party code may fire these actions with unexpected values, so the parameters are not type declared. When $post is omitted it is looked up from $post_id. Passing anything other than a WP_Post as $post, or a post that cannot be looked up, is incorrect usage and nothing is flushed. $post_before is only considered on wp_after_insert_post, where passing anything other than a WP_Post or null is incorrect usage and the value is ignored.
