Because on the PC, Nvidia only exposes high level targets for the shaders. Even PTX, the assembly you might be familiar with combined with cuda, isn't actually the device's asm, but instead it gets compiled down to the device's asm using a full compiler. It's poorly named and more a compiler IR than an asm.
