Google Ads Carousel "People Also Considered"

The folks at SEMRush spotted a new test format for Google Ads in the mobile search results. This one is in a carousel format where you can swipe left to right between ads and this carousel is named "people also considered."

I don't think I've seen this before, nor can I personally replicate this on my testing devices. SEMRush posted a video of it in action on Twitter.

Here is a still shot:

Have you seen this ad format before?
