how to limit edit_form_after_title hook to page and post edit only?

1. Personally I’d use a different approach, because @Shazzad‘s solution seems too much global dependent, and @s_ha_dum‘s needs 2 hooks instead of one.

   I’d use get_current_screen function to get a WP_Screen object, then I’d look at its property to run (or not) something after the title:

   function do_something_after_title() {
       $scr = get_current_screen();
       if ( ( $scr->base !== 'post' && $scr->base !== 'page' ) || $scr->action === 'add' )
           return;
       echo '<h2>After title only for post or page edit screen</h2>';
   }
   
   add_action( 'edit_form_after_title', 'do_something_after_title' );
   

2. Don’t know if there was any change during the time that passed from the original question but as of 4.0 you get the post as a parameter to the hook and all that is needed to do is to check the post type. If you wonder what happens when creating a new post the answer is that WordPress generates a dummy post if the post type set to the correct type.

   function do_something_after_title( $post ) {
       if( 'post' !== $post->post_type && 'page' !== $post->post_type ) {
           return;
       }
   
       echo '<h2>After title only for post or page edit screen</h2>';
   }
   add_action( 'edit_form_after_title', 'do_something_after_title' );
   

3. Check post type using $typenow and $pagenow global variables.

   add_action( 'edit_form_after_title', 'myprefix_edit_form_after_title' );
   function myprefix_edit_form_after_title()
   {
       global $typenow, $pagenow;
       if( in_array($typenow, array('post', 'page') ) && $pagenow == 'post.php' )
       {
           echo '<h2>This is edit_form_after_title!</h2>';
       }
   }
