It is not a flat value, it is a percentile value. And it adjusts dynamically to respond to any increase or decrease in attack speed that Olaf might experience.

Say Olaf gets bursted during his assault, his health will increase and therefore increase his attack speed. With his W activated this passive increase gets another boost because his W dynamically responds.
