standby and Oracle licensing

I am under the impression that a physical standby DB is licensed under the EE license for the primary and there is no additionl costs to run the standby. We are be told now this is not true by Oracle sales and they sent us a doc:

Failover: Nodes are configured in “cluster” with the first installed node acting as a primary node. If the primary node fails, one of the nodes in the cluster acts as the primary node. In this type of environment, Oracle permits licensed Oracle Database customers to run the Database on an unlicensed spare computer for up to a total of ten separate days in any given calendar year. Any other use requires the environment to be fully licensed. Additionally, the same metric must be used when licensing the databases in a failover environment.
• Standby: One or many copies of the primary database are maintained on separate server(s) at all times. These systems are configured for disaster recovery purposes. If the primary database fails, the standby database is activated to act as the new primary database. In this environment, the primary and the standby databases must be fully licensed. Additionally, the same metric must be used when licensing the databases in a standby environment.

What is your understanding of this?
"cluster" "failover" "standby"
They are really cuttign off their nose here again.
