It seems to work decently even with just one or two titles for popular titles, but less so for the niche.

For example, the title "Impro: Improvisation and the Theatre" by Keith Johnstone, linked by another article posted to HN today gives back the following suggestions:

- Truth in Comedy: The Manual of Improvisation by Charna Halpern - Steve Jobs by Walter Isaacson - 1984 by George Orwell - Harry Potter and the Sorcerer's Stone (Harry Potter, #1) by J.K. Rowling - Sapiens: A Brief History of Humankind by Yuval Noah Harari - The Alchemist by Paulo Coelho - The Tipping Point: How Little Things Can Make a Big Difference by Malcolm Gladwell - Dune (Dune, #1) by Frank Herbert

It's a bit unfortunate that all suggestions are fairly popular titles, which are fairly easy to find, while the unpopular or niche may be just as well written but a lot harder to find.

Within niche topics or books, it is also usually harder to provide multiple similar enough titles up front.
