[Q] Nexus 9 root/unroot flash to stock and OEM lock bootloader message

I want to root my Nexus 9 but I still want to be able to RMA it if there is a problem. (it is still locked and unrooted)

If I unroot and OEM lock the device with Nexus Toolkit what is the message in the bootloader? Will the Device State be Locked or Relocked ( or some other message besides Locked).
