The whole point of the torus is that it is a stable waveform in 3D as no other form is.

The double torus is obviously not stable in the same way or we would be able to blow double toroidal smokerings

and dolphins would play with double torus bubbles. ]]>

All I see the double torus model doing is making visible the dynamics inherent in the torus anyway.

I think it is confusing people to have them start talking about the double torus as though it is a separate form.

So my proposal is to acknowledge that all toroidal shapes have these dynamics and stop using the terms as it they are two different geometric structures.
