Configure planning security to restrict planners from seeing other org's data

Summary:

We are trying to use the Administer Planning Security function to limit planners to see only certain orgs' data in supply plan but unable to get the desired results.

Content (required):

A dummy job role was defined in security console and assigned to an user .Then in administer planning security we defined a data access set as shown in the screen shot below where we referenced the job role created above. A condition was defined at the organization level to limit this job role to one organization as shown in the screen shot below(under Condition field) but when this user goes to supply plan he can still view other orgs' data . How can we prevent that? If anyone has implemented this feature please share the steps on the configuration.
