It pretty much just proves what was known 10 years ago:

Combination antiretroviral therapy is now used to maintain viral suppression and prevent the emergence of viral resistance to antiretroviral agents. Such a treatment strategy translates into clinical benefit: multiple studies have shown that combination antiretroviral therapy reduces the risk of HIV disease progression and death.

The problem is you have to take the meds the rest of your life, can't do a, "I feel better, don't need them anymore". Kind of like depression :-( But that's why we are now hearing about breast cancer instead of HIV; of course, people in developing countries don't have access to the latest meds/treatments so they're still dying of AIDS.
