I see this a lot in the rural US with wooden fences but had no idea why it was done, but I guess its for the same reason (stability). Apparently they've done it since the 1600s.
Still, this seemed totally unecessary until I realized this mean they dont have to put any posts into the ground. No digging holes, which would be really nice when you're trying to fence up very large acreage.
