This is likely due to the fact that there is no load balancing decision made until after the HTTP_REQUEST event. If you want to dynamically check the number of active members of the pool, you'll need to do so during or after the LB_SELECTED event, which signifies that the BIG-IP has actually made a load balancing decision, and chosen which node to send traffic to.
