Pretty easy actually. Setup the test to prove the outcome you're after or pay for it and get the results you want. Comparing a 5W20 to a 5W30, or a 0W20 to a 0W30 wouldn't have yielded the results they were after.
In the video they compare 15-40 to 0-30. Some here say the oil flow to the head is the same for either. That's bunk. Thinner oils flow much faster than thicker oils as proven by the video.
In extreme cold 0W30 will get to the head faster than a 15W40, no doubt about it. I don't think there'd be much difference between a 0W20 and a 0W30 though, or a 5W20 vs. a 5W30.
