It's not really an apples to apples comparison to say that Oldham is like Sayid, because let's face it: Oldham's way of getting the truth out of someone is much less blood-soaked and screamy. But it *is* effective, though it's unlikely these Dharma Idiots believe that Sayid is from the future, especially after they vote to kill him. But have no fear! It will take more than a bunch of science-y hippies to bring our man down.
