Yea, this seems impossible. Passive cable length limit is 1 meter.

Per the USB-C specification table that discusses USB Type-C Standard Cable Assemblies that mentions a "≤ 0.8 m" limit for 40Gbps and 80Gbps cables:
The cable lengths listed in the table are informative and represent the practical lengths based on cable performance requirements.

There have existed 1.2m (4ft) certified 40/80Gbps cables on the market for a couple years now. A few 1.5m (4.9ft) cables have been certified in the last year. This cable is completely legitimate.
