I would imagine they would use that as the exception, since they are speaking on behalf of the Filthful and Disgraceful Slavebugger (which is supposed to be the head of the head of the householder). That would effectively bypass your headship.
However, they do expect women to take a totally bicameral role. The husband is supposed to make all the decisions, and is not allowed to let the wife think independently. The hounders make all the decisions for the men, and do not let the householders think independently. The hounder-hounders make the decisions for the hounders, all the way up to the Filthful and Disgraceful Slavebugger class. Ultimately, they are the ones that do all the thinking. Everyone else is supposed to take a bicameral role under them.
