I believe what he means is this:

When a Warg kills a traveling trader, it gets a new variable set on it, the name of something it slew. If a Gundabad Warg slew a Galadhrim Wanderer named Amrod, then I killed it, it would say: Gundabad Warg, Slayer of Amrod the Galadhrim Wanderer, was slain by recneps.
