How is the Activity Summary (Receipt tab) Updated after Return To Vendor is Processed?

We're looking into the Return to Vendor process in PS 9.2. After a Return to Vendor is processed, how is the Activity Summary - Receipt tab updated?

The PO line has total quantity of 8. This was originally fully received and Activity Summary - Receipt tab shows:

Qty Received = 8

Qty Accepted = 8

Open Quantity = 0

After the RTV is processed, the Activity Summary - Receipt tab shows:

Qty Received = 8

Qty Accepted = 0

Open Quantity = 8

After the items are re-received, the Activity Summary - Receipt tab shows:

Qty Received = 16

Qty Accepted = 8

Open Quantity = 0

Is the updated Qty Received value correct?
