Why are there no terms with the parallaxes of the Moon and the Sun, which are in the formula for a solar eclipse, in the formula for the maximum ecliptic latitude of a lunar eclipse?

The value of the angular radius of the earth’s shadow in this formula is used for the distance of the Moon, so it makes no sense to take parallaxes into account.
