It's possible that my mom was not the dummy I thought her to be in that moment. She might have played a sleight of hand where she unplugged the cord and cut it almost at the same time. My memory of that event is hazy enough that what I remember was thinking how crazy dangerous what she did was -- I might not have checked if the plug was still in the socket.
