Using two SAW filters in one package offers several advantages:
It reduces the component’s overall size, which is particularly valuable in compact electronic devices where board space is at a premium.
It also simplifies the design and manufacturing process, 
reduces the number of components on the circuit board, and is more cost-efficient.
