What this video covers
The thumb zone is the area of a phone screen a person can comfortably reach with the thumb of the hand that's holding it - roughly the lower and centre of the display. The far corners, especially the top, are a stretch or need a second hand. Put the things people tap most inside the easy zone, and keep the awkward corners for the rare and the harmless.
In the thumb zone the button met your thumb where it already rested - one easy tap. Stranded top-right, the same button needed a stretch or a second hand for an action you'll do constantly. Nothing about the button changed; only whether it sat where the thumb can actually go.
