What game mechanics are like this?

Off the top of my head, it’s the syringe kit in Farcry 4. Once you have the harvester skill that lets you grab two leaves from a plant at once, it will auto generate health syringes after you use one so long as you have green leaves in your inventory. At that point why would I need to bother with how many syringes I carry at once if they just replenish after each use?
