They are referring to visas that allow you to REMAIN in India for >1yr for each visit. This is otherwise referred to as a "Foreigners Residence Permit".
The regular business visa is valid for 10 yrs, but restricts you to 180 days on each visit. Hence, it does not require you to obtain an HIV test.
Hope this clears things up.
