The surrounded Executioner continued to wait for the three to attack. Even though he could end this battle in a flash, now that he had some of his restraints removed, he didn't do so since he wasn't sure if he might accidentally kill the three. Now that Richter ordered him to bring the three back alive, he just couldn't attack carelessly. Also he didn't really like the idea of ending the battle too quickly. Seeing as this was the first time he would be able to use at least seventy percent of his strength he wanted to get a better feel of it.
The Executioner would always do his job in the most efficient way possible. Seeing as his job was just basically killing traitors, he just needed to kill his opponents in one strike. He was also ordered to show the opponent fear before death, so sometimes he needed to slowly approach the opponent, and once it was established that he was getting scared, the Executioner would kill the enemy.
