Sonically, a power chord has power because human hearing hears the two notes as second and third harmonics and the brain inserts a first harmonic below them into our experience. We experience an E1 when A2 is played over E2. What we don’t hear is a third (9th or 10th harmonic) and the third forms the basis of the harmonic theories from the Period of Common Practice, and because the video is academic, those theories are the context in which chord progressions are discussed in the video.

Also a common misconception that hardcore punk bands only play power chords. A lot of bands are playing barre chords and hitting all the strings (imagine!). I learned most of the songs in the examples that way--whether the original guitarists did or did not, I don't know. Full disclosure, I am a self-taught, punk musician with minimal knowledge of music theory. But most hardcore punk songs are just pop songs sped up, so I don't see how one can have a chord progression and the other can't.

  As brudgers pointed out it's just how a chord progression is defined. A G major chord for example is G/B/D, if you don't have the B it's no longer considered a chord in music theory and if you don't have a chord you can't have a chord progression really. I don't really listen to this type of music but based on the quick snippets that were played only blitzkrieg bop had a chord progression. The other songs were power chords or what sounded like just single notes being played. If other songs in this genre you've heard are playing full bar chords than those would likely be considered to have a chord progression. Also, since most of this discussion, including the video, was around guitar, you can have a chord progressions with one person playing only power chords but someone else has to fill in the gap, like the bass or singer. It's over the whole arrangement not an individual part.
