I do suspect it is used for evaluations for sure. I suspect in some ways it is used in RankBrain, just not as many people think it is. I also suspect everything could have changed or can change in the future.
Microsoft may be testing shopping search filters in the product overlay within the search results. When you hover your mouse over a product and the overlay window comes up, Bing is showing some shopping filters to narrow down the products.
Here is a screenshot of this from Khushal Bherwani, I'll embed his video of this below:

Honestly, this almost looks like a rending bug to me. Why would Bing show product filters for a single product result? It doesn't seem to make sense to me...
