It has nothing to do with being a root server. You would have the same
problem if you were authoritative for foo.com and tried to configure
sub.foo.com as a forward zone.
Forwarders are only used when the server needs to recurse. The
forwarders simply override the nameservers in the delegation. Global
forwarders override all NS records, zone-specific forwarders just
override the NS records for that zone.
