Sugarbrie, read Marakanetz's article again. He's talking about a comparison of single-wiring with the jumpers against bi-wiring without the jumpers. His final configuration seems to be a single cable threaded through both pairs of binding posts, thus replacing the jumper with the cable itself.
If it is more practical to hook one cable up to the Speaker-A outputs and one cable up to the speaker-B outputs, there's no reason not to. When the speaker A and speaker B outputs are both switched on, they are tied together at the same point inside the amp.
