That's true. But there is one aspect which resonates with "organizing your political power in the same manner as organizing your authority over the household". Exploratory nature of Vikings' expansions occasionally meant that they were not restricting their chances to raid while the balance of power favoured them. In other words, they were treating things they could grasp and hold on as their own. This aspect might played out differently in different cases (and it did). At "best", this link shouldn't have been more than an association in Russia's case. But subsequent Mongol raides might have greatly inforced it.
