That page is mostly about auto-rotating carousels. Don't do that.
It's also about making your home page a giant carousel, instead of showing multiple things vertically. Don't do that, either.
IMO, one great use for carousels is when you have a product catalog with a bunch of category sections, like Netflix. Each category gets a header, e.g. "Action" "Family" "Romance" "Horror" and each category is a horizontally scrolling list of products, with the next one on the list half-visible on the side, so it's clear that you can scroll it into view.

Scroll snap can be pretty good for that.
