So there are actually two issues the article is confusing, but basically:
1. Turn on, move forward until you get to Connect to Wi-Fi.
2. If you’re on a private Wi-Fi network, skip this step and go to 3. If you're on an open Wi-Fi network, tap "Connect to Mac or to a PC with iTunes", then go back to the previous step, and Connect to Wi-Fi.
3. Complete setup, get to Homescreen.
4. Update to 16.0.1.
5. Reset iPhone from Settings.
6. Upon reboot, repeat 2. if needed, then complete setup and migration/transfer.
Clear as mud. Someone please correct me if I wrong.
