New Validation Users unable to see prior Invoices in Validation Client waiting to be validated

It has been our understanding that when a new user is added to /OTX/PDF01_ADM_VALA they are only able to see net new documents in the Validation Client. Is this expected? If not are we able to let new hires/users see prior documents? IE if I add a new user via this tcode, they only see invoices in the Validation Client from the date they were added. They will not see anything in Validation prior to today's date.
