Can't make heads or tails of what he's talking about. Is there a way he can point with a ruler at what he is referring?
I don't get anything he's saying because the objects he's referring to are not clear

Just came to agree with post. An animated video of the margins or something would help, but there isn't much on the screen when he's breaking down what's happening with Google Dev and I found it difficult to follow.

I thought it made sense. He's pointing at the individual elements inside the page. I guess it may not make sense if the HTML is complex or the structure is unknown. Perhaps it would be best if he simplified it.
In which case maybe a text tutorial could be helpful. https://css-tricks.com/what-you-should-know-about-collapsing-margins/
