I don't believe that but to each their own. I feel Sidious was fighting for his life and was beat outright. His knowledge of the dark side or even the force in general far exceeded that of Mace but Mace was the better swordsman and if Anakin hadn't taken a cheap shot he would've had his hands full with Mace as well. Sidious needed Anakin in that moment and only received his help because Anakin felt he needed him to keep Padme from dying.
