I don't know the details but building upon previous research is the foundation of the scientific method. Additionally, the scales were probably not named like that by the authors.
Imagine the single USB C port being 40Gbit/s or even 80Gbit/s (USB 4 Version 2). Given a nice docking station and some additional enclosures, you could technically even connect hard drives and run the phone as a low-power NAS. Or/and as a multimedia station for your 4K TV, I mean the integrated GPUs are usually more than capable enough.
A bummer that they stick to USB 2 speeds, even for most high end phones.
