I feel like you watched the video differently than I did because his whole point was about the prewash and the wash. The fact that the main washes where the pod gets dumped in, not during the pre wash for the for 15 minutes, which is his trying to be using powdered soap.
Or at least that was the first half of the video. The second half was about heat and wash cycles.

Furthermore, the amount of soap needed for a wash can vary, but pods provide only one amount. Powder or liquid soaps can be portioned appropriately.
