I referred to Terman`s 1955 edition, page 90, where Terman wrote:
"Where the load end of the line is short-circuited, that is Eload=0,
reference to Sq. (4-14) shows the reflecction coefficient has the value
-1.0 on an angle of 0-deg. = +1.0 on an angle of 180-deg. As in the
open-circuited case, the reflected wave has an amplitude equal to the
amplitude of the incident wave. However, the reflection now takes place
with reversal in phase of the voltage and without change in phase of the
current."

Of course, in the case of the open=circuited load, the reflection takes
place with reversal in phase of the current and without change in phase
of the voltage.

Terman`s writing has stood siuccessfully unchallenged for at least 50
years.
