empty forwarders in zone stanza effectively cancels global forwarders.
from the arm:

"If no forwarders statement is present or an empty list for forwarders is
given, then no forwarding will be done for the domain, canceling the
effects of any forwarders in the options statement."

				
			
		
	
so you can assume the same behavior for that zone as if you had no
forwarders defined.
