Ummmm ... when an elderly and distinguished scientist says something is impossible he's nearly always wrong ... A nic card has an isolating transformer rated to some 1000v between it and the cable. For the 240v to escape A it needs a faulty transformer on A, then to infect B it needs another faulty transformer on B ....
