Are you confusing a direct conversion receiver with a direct sampling receiver? A super-het (K3) or direct conversion (KX3) receiver is a heterodyne system. A direct sampling receiver is not.
It kind-of is. There has to be some kind of digital local oscillator in the electronics following the ADC which is used to heterodyne the signal down to baseband or a lower-frequency "IF". True, it's all done with ones and zeros but it performs the same function as an analog local oscillator and mixer.
