Maybe you're missing the 'Uranus axis of rotation is super tilted' part? Its equatorial plane (along with its rings) is not at all 'parallel' to the ecliptic, that's what the toplevel comment is pointing out.
“Near the solstice, one pole faces the Sun continuously and the other faces away, with only a narrow strip around the equator experiencing a rapid day–night cycle, with the Sun low over the horizon. On the other side of Uranus's orbit, the orientation of the poles towards the Sun is reversed. Each pole gets around 42 years of continuous sunlight, followed by 42 years of darkness.”
Very different from Earth! Wow.
