This could be a terminological issue. There used to be a lot of confusion around various kinds of vegetarianism a couple of decades ago. Then things basically settled, and "vegetarian" without further qualifiers became understood as "no meat" (and no fish and seafood). Dairy and eggs are allowed, unless specifically ruled out. Traditional western cuisine was largely vegetarian in this sense. Meat used to be an expensive luxury, and most people didn't eat it every day.
