The property is used to ensure the CDN is serving legit content that has not been tampered with.
Also, the common argument for this technique that CDN lets you cache content so that users don't have to re download it every time. But I think it could also be done at the HTML level by precising a hash value of the file that we want to integrate (I stopped web dev for a few years I don't know if that has been added to HTML ?)
