The jugs with pointed bottoms were for bulk shipping. They were set upright into racks on board ship or tied together at the neck and slung across a donkeys back.
Once at the merchant's shop it would be poured out in smaller quantities for end sale.
Sorta like the 55 gallon drum of the eastern Mediterranean.
Makes sense. Shipping containers would have to be tied down somehow, so if they had holed planks already installed on cargo ships they would save handling and time. The pointed jugs could also be tied together in freestanding masses of three or more that would be perfectly stable.
