Need help for importing from saved views (Level 2 Sprint 1)

In 1.3.6.2 Create Build Country Saved View 

Create a saved view for importing: 

Module Name: SYS06 Country Details 
Saved View Name: Build Country
Include: Code, Region, and items 
Make sure to select SHOW for the Code line item and save the view. This will ensure that as new line items are added, they will not be included in the saved view and imports will be faster. 

 

I don't understand why it is saying to show only the code line item, when in section 1.3.10.2, it says you need the region. On top of this, why would you need to import from a saved view when your primary hierarchy has what you need? This also goes for the the G1 Region import as well.
