Well, I might not be the guy you are referring to, but I grow mine on a fence. Each plant (or region since they've spread) has a bamboo pole to train them straight up and then over to the fence. This way I can trim off the lower leaves to allow weeding and pruning excessive new shoots.
They've already hit the top of the 6ft fence and when 2 or 3 bines wind around each other they can support themselves in free air for about another 3ft.
They might not produce as good as a single tall growth, but it's free and (almost) zero chance of falling over.
