For one thing, that initial arrogance should've gone away as soon as Revan resisted his telepathy and then knocked him on his ass. Unless if we're going to conclude that Vitiate is used to having people negate his TP on a dark side nexus and ragdoll him against the floor.
I'd imagine he was using minimal effort attacks to slow Revan's approach so he'd have more time to charge his FLS, but it's just speculation. It could also be surmised that he was testing Revan for some reason, he does like to test people, but these are just ideas.
