The author has neglected to mention that the mixing process is actually a "multiplication" process, which becomes clear when we visualize the 4-diode mixer as reversing the polarity of the input signal in time with the reverses in polarity of the driving, (local oscillator), signal. That much is intuitive. The creation of sum and difference signals is a bit less intuitive.
