Show shortcuts to other category product?

Hello.

The catalog is constructed by a principle One good-several categories, from these requirements and stopped on HikaShop.
I have in the general settings:
"To show on page of the goods of the button of transition to the following goods in category" (Show shortcuts to other category product).
Having come on Goods page into the categories Drawing which except this category belongs also to categories Authors and Nonconformists , we should thumb through the goods only the categories " Drawings ", and transition on all goods of the author to belonging different categories actually turns out.
I can not understand in what business, and transition "to the following goods in category" it is extremely necessary.

Thanks.
