Misleading statement in "Token-aware Routing" section

Description

I was talking to a customer and they clearly got confused by this statement in our C++ driver doc (https://docs.datastax.com/en/developer/cpp-driver/2.2/topics/configuration/#token-aware-routing):

"Token-aware routing uses the primary key of queries to route requests directly to the Cassandra nodes where the data is located. Using this policy avoids having to route requests through an extra coordinator node in the Cassandra cluster."

This gives them impression that there could be multiple coordinators involved in a single read or write operation, which I told them is not true.

I quickly searched our Java and Ruby driver docs, and didn't find this "extra coordinator" being mentioned anywhere else. So this seems to be C++ driver doc issue.
