Buddy, you're skipping the part where Conor repeatedly announced publicly and directly to MMA media that he was going to get tested twice, and be good to go.
He lied about it so much that USADA was forced to come out and make a rare public statement back in March saying that was patently not true, they had not spoken to Conor at all, and he would have to spend 6 months in the testing pool.
Considering he was telling fairly egregious lies about it, people were skeptical if he would get back in the pool - then if he can pass the tests even if he did.
Presumably Conor has been testing privately and is clean at this point, or soon, and that clears the way for him.
