The current is induced behind the UPS might be enough to kill the power supply. It never killed any of my machines though. I even have had one a switch burning after the neighbour's house got hit by a lightning. While the switch was really burned, some of the connected machines survived with no damage at all while some others have had the network interface killed. The UPS was an online version and no other damage via the power supplies has occurred. As I said before, this strategy only makes sense in an environment with a lot of thunderstorms and lightning strikes.
