Do you want a given product to reference a list of other products that match on a given value, but do not want to maintain the reference list yourself? In a fashion shop this could e.g. be a reference to products with the same style. Other usages could be grouping products by color or similar. With Referencd you can select which metafield value should group products together (e.g. style), and the app will update and maintain the list of references for each product in another defined metafield.
