What does traceability one step back and minimum traceability one step forward mean?

Can anyone help what does traceability one step back and minimum traceability one step forward means? SQF 2.6.3.2 Testing shall include incoming materials (minimum traceability one step back) and finished product (minimum traceability one step forward). Testing shall be carried out on products from different shifts and for materials (including bulk materials) that are used across a range of products and/or products that are shipped to a wide range of customers. Does it mean that I need to choose product from each shift and conduct the mock recall?

Guidance 8.1 -
 

 

The supplier must have a process in place that enables them to trace product to their customer (one up) and back
to the material supplier (one back).  A written procedure must be documented to show how this is accomplished.  
The product trace system must account for raw materials, packaging materials and processing aids used that may
impact on food safety.
