Since rho represents the fraction of forward voltage that is reflected,
what does a negative value for rho indicate?

rho = +1 means there is a zero degree phase shift in the reflected
voltage.

rho = -1 means there is a 180 degree phase shift in the reflected voltage.

So in other word the sign sometimes indicates phase, and other times
indicates a direction in propagation depending on which hand is waving..
Thanks.
