I was under the impression that the supply bonus work only for the troops led by the commander with the item

If you look at the supplies used value for a province with multiple commanders carrying Bags and with few attached troops, it's not at all uncommon for this number to be negative. I routinely will send (as my AAR demonstrates) 1-2 combat commanders / mini-SCs into a province along with many (hungry) Jotuns under their command. The 1 or 2 commanders, even if they have Bags, cannot possibly feed all the Jotuns they are leading, nor can the province support armies of giants in the numbers that I routinely field. Yet, the 2-4 priests that also accompany such armies, each carrying a Bag (and usually a magical artillery device as well) indeed do add their food bonus to the needs of the army, preventing anyone in the army from starving. Trust me, it works. Without all the Bags, my Jotuns would be in sad shape (GoH notwithstanding).
