Restricting Queries in HR: Compensation Management User Group

I am trying to restrict the Infoset /SAPQUERY/HR_XX_CM_03, which contains salary/compensation queries, assigned to User Group /SAPQUERY/H0, from being accessed by anyone. In SQ03, user group /SAPQUERY/H0, there are no users assigned but users with access to SQ01 can select the user group /SAPQUERY/H0 and access the queries tied to infoset /SAPQUERY/HR_XX_CM_03. Why are users able to access the infosets of the user group when no users are assigned to the user group?
