"They're not working royals,” Victoria says in the episode. “They don't have any kind of public profile. And that really shifted the tone for me into this ‘is this a personal thing?’ This is about their family.”

Victoria goes on to explain that the Middletons appearing in the video was Kate “showing us her village”.
