Do you have a source?
Because precedence and the rules disacgree. Here's a recent example:
As the regulatory body that sanctioned Mr. Tibau’s bout on November 7, 2015, the Comissao Atletica Brasileira de MMA (CABMMA) has recognized USADA’s sanction and, in accordance with the CABMMA Anti-Doping Policy, reversed the outcome of Mr. Tibau’s bout from a “win” to a “loss.”

Pre USADA the fight would have been overturned to a NC, but part of the harsher penalties is it's now a LOSS for the cheater and a WIN for their opponent.
BTW, I love how Hunt is after Lesnar's full disclosed pay!
"Hunt said he has asked UFC officials for half of Lesnar's record $2.5 million guaranteed purse or to be released from his contract effective immediately. Hunt added he has yet to hear from UFC." ...
"Hunt changed his tone later Friday night in a profanity-laced tweet, saying that he now wants all of Lesnar's guaranteed purse.
"Well I wanted half but have changed my mind cheaters shouldn't get s--- I want all of it cheaters don't deserve s---," Hunt wrote in his tweet." [SOURCE -
