That page is giving information purely from the customer's point of view. So that bit about the recommendations is saying that if you create a tag for a product - let's say you tag a product as "romance" - then the recommendations that Amazon makes to you as a customer are more likely to be based around other products with the tag "romance"
It does not really tell us much about the purpose of tags from the seller's point of view - for example, from this page you cannot tell whether the number of people who have tagged a product with the same tag, makes a difference to how that product appears in the search rankings. But all the same, I assume it does.
I suspect that a book with a greater number of "romance" tags is going to appear higher in the results that appears when you click on that tag.
For example, when I'm on the page for "A Modern Witch" I can see that there are 6 tags attached for the word "witch". If I click on that tag, the first book that appears in the results page is something called "Ultimate Power(Special Edition)"
. When I check how many tags that has, it has 91 "witch" tags. "A Modern Witch" appears way down on that list, as it has fewer tags.
