Pwnagotchi IP used for ssh is different than RNDIS IP

When I set up pwnagotchi , I use 10.0.0.1 for the rndis adapter on my win 10 box. But when I ssh into pwnagotchi, I use 10.0.0.2. I am confused about where the 10.0.0.2 comes from. How did pwnagotchi in manual mode decide to set its ip to 10.0.0.2? When I set the rndis adapter to 10.0.0.1, am I not configuring the adapter on my windows machine only?
