What makes a catalyst a catalyst is the fact that it doesn't get changed while causing an event. If it was simply something that starts an event, there are plenty of other names for those. A catalyst has to stay unchanged, therefore, either he's lying, or BW didn't check their facts. Not checking your facts boils down to bad writing.
