Biwiring works.

Since the HF and LF speaker terminals accept only HF and LF components, there are no LF signals on the HF line ( and vice versa ) which cleans up IM distortion.

Amp output is full range, on both A and B terminals, the signal is full range on both HF and LF speaker terminals.
Bi wiring is a myth.

That's incorrect according to Ohm's Law. The high impedances in the network branches reduce full spectrum pass through in the associated cables.

Not a myth, but if it doesn't work for you that's ok too.

The signal is not "full range" on each wire, due to the high pass and low pass filter elements at the end of each wire.

HF travels across the wire connected to the High pass filter, while LF is attenuated as per filter slope.
LF travels across the wire connected to the Low pass filter, while HF is attenuated as per filter slope.

If both filters slope at 6dB per Octave, then the LF signal on the HF wire is 6 dB down for each octave below the High Pass crossover frequency. Similarly for the HF signal on the LF wire -- there is a 6 dB drop for each octave above the Low pass crossover frequency.

If interested in bi-wiring being modeled with comments check the link and scroll down the page.

Unfortunately, the analysis in "modulation muddle" does not take into consideration any filters.

Yes, well, as stated (and based on some facts, it would appear). Bi-wiring can work.

This schematics shows that bi-wireing just moves the "jumpers" from the back of your speaker to the amp connectors. Please note the green area illustrating the connection/location of the jumpers.

Bi wiring is essentially extending the the jumpers found on the input terminals, not too hard to visualize. It will have a sonic effect by introducing more resistance and capacitance to the circuit. Whether or not that is better is just a matter of opinion.

Makes you wonder what's so difficult to understand. Seems pretty simple to me...

Incorrect Bandy. In the HF, only hi-freq. will ever pass the circuit. Then, LCR is greatly affected.

And as Ripblade said:

Not a myth...
This is the correct answer. +1

Just to clarify a thing here;
bi-wiring is most beneficial if of course the 2 cables are not the same. (since they won't pass the same signal)
