No they're not lift cables, they both run to the street lamp so pretty sure they're both power (the one across the road could be telegraph) but looking at google street view
Morzine, France - Google Maps gives a different angle. None the less I don't think that the winch cable could have been more than 20metres from the wires.
I do seem to recall that as soon as he'd taken up the slack on the cable it was 'up and away' as I remember dangling over the valley for a bit before being winched the rest of the way in.
