You're as in you are, not your as if it belongs to me. The point is others lost or left the weight class. He did fight and being undefeated is what moved him up in the rankings.
He hadn't fought in 2 years, and when he came back beat an unranked fighter (doesn't move you up )
So no he hasn't fought.
Bendo and Cerrone left the rankings.
But then we got killers in Edson and Tony who came into the picture.
Khabib is 7-0 in the ufc, was ranked #5 after his last win vs a ranked opponent, and hasn't beat a ranked fighter in over 2 years since.
Tony is 9-0, and just beat the #2 LW, and is ranked behind Khabib.
I'm just trying to grasp the logic here
