Of course they would say that. I don't own a rack yet, but I have been researching them and from what I can tell, most of the 3 and 4 tub models look like they have one long piece of flexwatt that runs across the shelf, up the side, across the next shelf, and so forth, and only has one wire. I haven't gotten into the specifics of flexwatt yet, but I'm pretty sure you can actually run a fairly long piece on each wire...
