Why would you expect that?  Do you mean that if you had an 
allow-recursion statement that listed the only clients who were allowed 
to request recursion, you'd expect it to ignore it?  "recursion no" is 
just a shorthand for "allow-recursion { none; }".

The way to think about forwarding zones and global forwarders statements 
is that they simply tell the server to query specific IP's rather than 
(or ahead of) the delegation records *if* it needs to recurse.  But when 
recursion is disabled, this "if" doesn't apply.
