It addresses it with counter examples that indicate that a "hierarchy of quality" is not something that really exists in consumer products. The fact that so many companies chose not to make the hierarchy clear is an indication that such a hierarchy isn't valuable to them.

The fact that Apple has abandoned the "one phone, one tablet" model indicates to me that it hasn't been a valuable strategy for them.
