I would have described flipping it over before collapsing. The title seems a clickbait, but is no quite that. Keep in mind that most of the iceberg is off camera, as shown during the first minutes. It lost 80% or 90% of its total mass but most of it isn't seen until the end, when the iceberg goes back to the right.
