Can you kill him a second (or third) time in a week and use extra rolls on him for loot? I know you can use an extra roll on intial kill....

LFR/Flex allow re-coining. World bosses do not, I guess since they drop normal-mode loot. There was a fairly recent change to keep re-offering the chance to use a coin if you didn't on the first kill that week of a world boss. So if you killed ordos but had zero coins, you could re-kill and coin that week.
