Yep, Ay's fighting style is supposed to be extremely aggressive, in order to gain the initiative in the fight and force his opponents on the defensive.

You also have to keep in mind that he really wanted to kill Sasuke. It was basically at the top of his priority list, since he wanted to avenge his brother no matter the cost.
