When Brisco and Curtis were questioning Eddie Murrows in a bar Murrows recalled events of 1965 including the time in May 25th 'when Ali took Liston in one' (the fight actually took place in February 25, 1964). He couldn't have possibly remembered the name 'Ali' because at that early point in his career Muhammad Ali was fighting as Cassius Clay. Clay changed his name to Muhammad Ali later on.
