What I objected to was calling it sampling.
You can use a switching modulator to perform amplitude modulation, but that's not the same thing as sampling.
Mathematically, a switching modulator can be shown to produce the desired AM wave plus the square wave and a bunch of harmonics. The square wave and the harmonics can be filtered out. When you do that, you get the proper, continuous-time amplitude modulated signal. It is not a discrete-time signal, it is not sampled.
