VPN Server/Client non-cascading

Question regarding my IP address whether VPN cascading is on or off.
My WG Home server ip: 1.1.1.1
My Beryl WG server ip: 2.2.2.2
My cell phone ip: 3.3.3.3

If my Beryl uses WG client to connect to my WG home server, every traffic through the Beryl will have public IP of 1:1:1:1, correct?

If my cellphone VPN to my Beryl WG server, while Beryl is connected to my WG Home server without VPN cascading turned on, does it have public IP of IP 1:1:1:1 or 2:2:2:2?

It seems like if VPN cascading is turned on, the cell phone should have public IP of 1:1:1:1, suggesting without VPN cascading turn on, it’ll be 2:2:2:2?

Thanks in advance.

Yes.
VPN cascading on: cell phone IP = 1.1.1.1
VPN cascading off: cell phone IP = 2.2.2.2
