Indeed, from the changelog:+ Added farmhand AI to deposit crops into and collect seeds and bonemeal from chests marked by an item frame with a hoe

In light of this information it would seem that the suggestion is for farmhands to pick up seeds from a chest when they have none. Seeing as you already have to access their GUI to assign them to farm, this seems unnecessary as it only requires a little more effort to put seeds in.
