I discussed this a while ago with FBinNY and he set me straight on the issue of spoke tension during braking. It's what allowed me to visualize what would happen with a wheel laced using the pattern discussed here.

The only reason a standard cross-laced hub does not experience torque during rim braking (or when simply sit on the bike) is due to the trailing AND leading spokes on both sides of the hub. Without those spoke forces countering each other, the hub will be torqued when displaced by any amount (though even at rest, without trailing and leading spokes on the same side the hub is being torqued).
