From the security context point of view, 2 ADFs using the same application PIN are part of the same application. Each ADF then refers to the same local key reference number whose value and status is specific to each ADF. Figure J.1 illustrates it.

From the security context point of view, two applications use two different application PINs. Then the local PINs of the applications use two different key reference numbers, each one paired with its associated application PIN. Figure J.2 illustrates this scenario.
