This means that when a connection at CDG falls below a certain threshold, a “priority process” is automatically triggered for all impacted passengers at security and border/passport control.

At Schiphol when you are transferring if you have less than half an hour when you reach immigration you get automatic priority in the security line for transfers. The flights affected are listed and you use a bypass line.
How does CDG manage it? Since transferring passengers go through immigration in a special transfers only line, it is already fairly quick but this would help those with very short connections; it would make since for it to be available to anyone with a short connection not just AF as it is in Amsterdam.
This is what Air France says:
Upon arrival of their inbound flight at Paris-Charles de Gaulle airport — if not before — customers receive an SMS and an email informing them that, due to the short time available to reach the boarding gate of their next flight, they are eligible for priority access at security checks and border control. This message will soon also be sent via a notification in the Air France mobile app and a WhatsApp message.
When customers arrive at security checks and border control, their boarding passes are scanned and Groupe ADP’s customer service staff are automatically notified of the short connection. They then offer priority access.
