If I understand your question correctly, I explain it like this:
Gasoline has vapor pressure specifications. But when ethanol is included in gasoline, the normal vapor pressure specifications are difficult to meet. So there is an allowable exception to those specifications when ethanol is in the gasoline. Even with ethanol in the gasoline there are still vapor pressure specifications that must be met based on the amount of the ethanol component. The amount of ethanol determines how much higher vapor pressure is allowed. The revised vapor pressure spec value is calculated from the table you attached. This new vapor pressure is specific to the composition of your gasoline and is the amount of 'vapor pressure waiver' allowed if the gasoline does not meet the normal gasoline spec.
