Definition of magnitude

This is unclear:

Technically, the magnitude is computed as follows: draw a straight line between the centers of the eclipsed body and the eclipsing body (or shadow). Find out how large a fraction of this line within the eclipsed body is in eclipse; this is the geometric magnitude of the eclipse.

On first reading, I took it to refer to "the centers of the eclipsed body and the eclipsing body", exactly as written: i.e., the center of the Sun and the center of the Moon, respectively. That line runs straight from the Sun to the Moon and, in a total eclipse, to some point on the surface of the Earth, and the length of it that it within the body of the Sun tells us nothing about the eclipse.
