Itachi could make Amaterasu have instantaneous burn power, but just like that time it will take more chakra compared to the normal usage of Amaterasu. He was most likely sick at the time and used two full power Tsukuyomi's and one full power Amaterasu and he had to shut his Sharingan off so using the full force of each tech while sick will be an issue. But if Itachi isn't sick here then he can use them more most likely. If one of the paths is hit with the Full Force Amaterasu then that path is done.
