The switch had to be operated deliberately, but still a UX fail on a modern aircraft if cutting off fuel to the engines does not result in an audible alert/alarm which both pilots can hear - especially at that altitude.

Are you sure there wasn't an audible alarm?

The switches were re-engaged within 10 seconds so isn't it possible they quickly heard a warning alarm, realised the issue and fixed it? (Of course, not quick enough in this case)
