Zaku pointed his hands at Sasuke, then fired in the next. For all we know, Sasuke isn't faster than the attack, he just moved out of the range of fire faster than Zaku perceived.

Basically pretend Zaku's holding a gun pointed at Sasuke. If Sasuke ducks and the bullet misses him, it probably isn't because he's faster than the bullet. It's because he dodged before the trigger was pulled.
