Sorry if I'm saying the obvious, but I think what Eli was trying to explain in particular is that the filaments of the two double triodes need to be at different potentials if you use direct coupling - they are acting as cathodes, after all. The only way you can arrange this is with separate filament supplies, one of which could be a battery, of course, but it doesn't have to be.
