I was wondering this myself (we use F5) but if he doesn't have the budget
for a  redundant pair of F5's )they are pricey...) then he may be trying to
get resilience this way....

That said a single front end apache server with mod_proxy and load balanced
across N nodes (depending on front end firewall too) might be simpler
overall....
