Collapsable In This Video SERP Feature Now Triggering in Multiple Position in SERPs

The In This Video SERP feature which used to trigger for the 1st result in a video carousel on mobile is now popping up for multiple videos on the SERP, some of the results are collapsed and you can expand it. Some of them have thumbnails while others don’t, I think they are testing a lot with this format and after their tests are concluded they will likely settle on a primary format for this SERP feature.

Sample Query: Try searching for how to make your own website on Mobile or Desktop. I was NOT able to trigger the multiple In This Video SERP feature from US or Australian SERPs.
