I'm willing to bet that this is one of those sketchy knockoff cables. The usb-c standard, called USB power delivery doesn't support 10 amps. Likely it never could because it would require thicker cables and more heavy duty connectors than what USBC actually has. Anyone who knows anything about basic electronics already knows this, more specifically what happens when you put too much current through a cable that's not rated for it.
All I can say is that I hope there aren't devices that try and actually pull 10 amps through a cable like this, it would probably not end well.
