The author never said otherwise, their whole point was to explain, that moving the dock from the left, which is in close range to the hot corner and button to activate the Activities screen, to the bottom, means that you now have to move the mouse a much larger distance if you want to access the dock with the mouse. And since GNOME doesn't support an auto-hiding dock at the bottom, there's no way around that when you use the mouse.
I mean I'm just rephrasing what the author already wrote, because I think they made their point pretty clear to begin with.

Every other modern and popular desktop on this planet supports auto-hiding docks/panels and nobody asks GNOME to force an always visible dock on you.
