A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

If you think much about the Order Item use case, you'd probably soon realize that, before you order an item, you should first query to make sure that the item is in stock. So, while the user is interacting with the "Order Item" use case, during part of that process, you'd be executing the same process as "Query Item In Stock." That would make it seem as if the Order Item use case was the "actor" of the Query Item In Stock use case.
My UML (and certainly my terminology) is a little rusty, but I believe this is considered a "depends upon" relationship (perhaps it's an include).
