It would appear that it's looking for all sales order items that do not have a related sales item distribution record (except for those sales items created by the integration user).  For each of those, it's creating, and eventually inserting in bulk, a related sales item distribution record whose date confirmed is either the confirmed or requested delivery date shown on the sales order item.
