They probably had the AT disconnect annunciator flashing away until the end.
When I see that AT disconnect flashing for more than a few seconds, I know the person I am sitting next to is overloaded and has lost SA. It's interesting experiment to see how long before they attend to it, it can be quite some time. Occasionally they won't even notice I've reached up and pushed the annunciator to cancel it.
