Does SFHA 6.2.1 supports RHEL7 ?

Under assessments => Install and Upgrade :

When I select SFHA as a product and select 6.2.1 as product version you are installing to , I cannot see RHEL7.

But

When I select SFHA as a product , select 6.2 as product version you are installing to and platform RHEL7 then under Platform Configuration I can see 6.2.1 supported RHEL7 GA. what is this ?
