Your setup here isn't quite complete to make valid assumptions because you have load balancing methods between pools configured for the wideIP as well as load balancing methods within the pools.

 

How are you load balancing at the wideIP pool level? I assume the above "Prefered: Topology, Alternate: Round Robin, Fallback:Return to DNS" is the load balancing config within the pool?
