No. The focal length is 90mm, not the distance away. A macro lens will give you a life-size image (1 cm in real life is 1 cm on the sensor), 1:1. With 90mm, you can stand further away to get life size. Most people prefer that. With 55mm, you have to move closer to the subject to get the same life size as 90mm.
