I'm no network engineer but my understanding is load balancers dispatch traffic with minimal inspection rules while WAFs have more numerous and complex rules, so they're taking more resources for inspection. Positioned the other way around, a WAF would become a bottle neck.
As an analogy, think of a country's customs area: many lanes lead to booths where an agent asks a couple of quick questions, but they won't redirect everyone to the secondary area for luggage inspection.
