Oh, those that think the UFC and USADA will collude to give Jones a short sentance or even clear him might want to read this article.
Theres a little thing called WADA
Former EFC champ Demarte Pena found guilty of doping, banned for four years
He was provisionally banned, but then cleared of intentional doping in May after SAIDS tested samples of legal supplements that he had been using, and found them to be contaminated with banned substances. Seemingly cleared of all wrongdoing, Pena would go on to face Sayed again on 16 December last year, landing several powerful punches and one head-kick en route to a dominant victory. In reality, as shown in the CAS report, Pena had yet to stave off an appeal from the World Anti-Doping Agency (Wada) against the Independent Doping Hearing Panel’s decision to let him off with only a reprimand.

In a nutshell..
Demarte Pena tested positive and South African Anti Doping charged him with a violation. In the end a contaminated supplement was blamed and he was totally cleared.
So WADA, unhappy with the decision of the tribunal and South African Anti Doping appealed it to the Court for Arbitration in Sport (CAS). They won, and he was suspended for four years.
(Pena provided 3 tubs of a supplement to SAIDS, two were opened, and one was factory sealed. The two opened ones, contaminated with the substance he tested positive for - although not in quantity that would be consistent with the levels found in his samples - the third, sealed container, totally free of all prohibited substances. He had "contaminated" the open ones himself)
TLDR
USADA are signatories to the wada code and expected to follow their guidelines. Although the UFC program is independant it would still have a bearing on other cases, if Jones was "cleared" other athletes could theoretically cite his case as precedent. So If USADA do something dodgy and basically clear Jones, WADA could potentially appeal it to CAS, they have done it before.
