That's one possibility.

DNS servers that your local named will query for all domains it
doesn't know about. Queries for the local domains are served from the
local zone files. All other queries go through a different procedure
which usually requires sending queries to the root name servers and
several others. This information is cached by the querying named
instance for a while.
Instead of having your named make queries to root name servers, .com
nameservers, and then google.com. nameservers, when you use forwarders
the servers that you have configured as forwarders are queried.
Bearing in mind that your ISP has many users who probably ask for the
similar DNS information all the time, it is very likely that their
name server has this information already. This is why named.conf
suggests that you use *them* as forwarders.
