Not what the author is doing here, but you can also connect them over standard Ethernet. Any standard USB-C to Ethernet adapter will work with the iPad automatically.
Came as a surprise to me a few years ago when I first ran a that it.
It's so convenient to have USB-c power, audio, storage & network on a single cable. iPadOS can't detect headphones that are unplugged from 3.5mm audio jack on a dock, so it's better to connect headphones to dock via USB, to enable quick switch to speakers. There are right-angle and U/180 degree USB-c adapters to keep the cable out of the way.
Anyone with a USB-c iPad requires USB-c DAC to connect headphones, with or without a dock. Docks can include 3.5mm audio jack and/or USB-c port. iPadOS software response to physical disconnection of headphone cable varies between 3.5mm audio jack or USB-c DAC. If 3.5mm is unplugged from either DAC or dock, iPadOS will continue to suppress on-board speakers.
Android apparently (AFAIK, still) uses a poorly crafted regex to identify ethernet adapters, so most usb ethernet adapters don't work on Android, despite having drivers, etc.

Makes sense, I had simply never considered it.

RPi 400 keyboard + iPad VNC also works, or HDMI-to-USBc via iPad app, https://www.reddit.com/r/ipad/comments/utvfcu/my_ipad_mini_r...
That's fine if you have a USB DAC lying around, I guess.
Required to connect a headphone directly to a USB-c iPad or iPhone.
I thought this was about some kind of dock...

The author is plugging a USB-C to USB-C cable between an ipad and an RPi, and having them speak Ethernet.

I thought this was because Google don't build the kernel with many USB ethernet drivers?
CyanogenMod used to (I assume LineageOS still does). I recall being able to use a USB ethernet adaptor on my phone with CM because of this.
I haven't tested this in a long time. Perhaps I should!
