My take on it is that before closed loop the IPQA is simply monitoring the process; thus, reporting on the error conditions(NDE) based on the requirements not taking action on the metal. The Closed loop is actually taking action on the metal; thus, altering the metal condition (DE).

An IT analogy would be equivalent to an Intrusion Detection System which monitors the network for threats and reports on them but takes no action on the threat detected; thus the traffic is not altered. On the other hand an Intrusion Prevention System not only detects the threats but takes action to block the threat; thus, altering the traffic that passes thru the network.
