Item Rule Set to define an attribute to only one organization

Summary:

We are trying to define the value for [Item].[General Planning].[Planner] when creating a new item, but only to an specific organization that is beeing assign by another rule.

Both rules work correctly but specific planner is assigned to all organizations:

Eg:

Rule 1 : Assign to specific orgs: assignedToOrg("MASTER ORG") - Return "ORG_1", "ORG_2") // This is working correctly

Rule 2: Assign specific Planner : assignedToOrg("ORG_1") - Return: [Item].[General Planning].[Planner] == "Planner 1" // This sets "Planner 1" to all orgs, as the validation that the item is assigned to org_1 is correct.

How to specify scope or target org?
