And yes you are correct, this is done as a way of inhibiting duplicate links from forming, and thus, hurting the store's SEO. With this being said, Instead we give all the SEO juice to the root links so that this individual page shows as high as possible in Google as opposed to having 10 different pages shown on the 20th page for example.
Have a look through the guides and see what works best for you.
Does that work for you? Let me know
All the best,
