Are the duplicates separate products (have a separate url)?

Are the duplicates separate products (have a separate url)? 

Duplicates are copies of the original product, differing from the main product (parent), e.g. title, photo, or any parameter/parameters chosen by us. Duplicates have the same url as the parent, so there is no possibility appear in the ad for a duplicate product next to the main product.

Duplicates allow us to achieve better results in ads by more accurate matching to the search phrase. Thanks to duplicates, we can also conduct A/B tests of products that convert better.
