I think they just mean wireless charging is supported but a MagSafe mount/holder won’t work because the case doesn’t have the proper MagSafe “magic” in it (that ring you see on a clear iPhone case).
It will work - the magnetic interaction happens through the plastic, just will be very slightly weaker than one with additional magnets due to the tiny gap. The video shows it mounted on a MagSafe charger
