It is not the same on Android, at least not on Pixel devices. If you turn off auto-rotation, your screen will stay locked in whatever orientation (vertical or horizontal) you did so in.

One can also still rotate their screen by tapping a little rotate icon that appears while rotating while auto-rotation is turned off.

Yes, I believe this is correct as the terminal you tap/place your card/phone near transits enough power wirelessly to read the NFC (F) data or so I have read. The NFC (Felica) + Osaifu-Keitai + Suica/Passmo system is quite interesting and super reliable.
