Yes it does. Because Itachi could have easily reacted when Sasuke said "begone with the thunder." Sasuke's hand went down after that. And you say barely moved, when it went all the way from above his head to around waist length. If Itachi can trade blows with Sasuke, that means he can react in time before Sasuke's hand finishes moving.
