Research scientists are not stupid that they would overlook the implausibility of a guy who says he went to prison but never had MSM or engaged in other risky behavior but somehow wound up with AIDS. Besides, many steps are taken to keep tests blind to subvert the effects of lying. Its the entire reason behind the MSM category.
In addition, HIV/AIDS tests are routinely done on prisons, something like once every 2 or 3 months, where the population is some 25x more likely than the general public to be infected. So often times, researchers will know the guys got HIV in prison and clearly cannot categorize them under heterosexual male (since there would have been no hetero contact in prison). The only choice they'd have would be IDU or MSM.
