What does "dual competitive advantage" mean in the hotel industry?

Please do correct me if i am wrong, Dual Competitive Advantage is when a company enjoys advantages over other competitors in terns of location, easy access of costumers and services.

Dual Competitive Advantage:

 This is achieved when the company manages to cut supplier opportunity cost through better  supply-chain and inventory management and yet manages to increase customer’s willingness to pay by providing unmatched value-added services
