They are just two separate credits for different situations.
The Notice 2013-70 is only referring to the §25D credit, which is only for personal-use homes. As that notice says, you can't use the §25D credit (Form 5695) for rental homes.
However, a completely different credit is the §48 credit (Form 3468), which is only for business/rental property. That credit CAN be used for rental property.
