is that it does not require an external power supply for the saving possibly size and

The second option is using an external supply. The motivation is to allow shutting
down additional circuits inside the Module in order to achieve an even lower floor
power consumption in lite hibernation mode (~150uA instead of ~250uA). In order
for this to be possible you should use an already available supply in the application
board or add a dedicated low quiescent DCDC converter for this specific use.
