This is the correct term. Necessarily because he writes iwth his left, doesnt mean that is his dominant hand. For instance, I write with my left hand, but dominate, or I am stronger with my right hand & side in general. I am, however, more accurate with my left. That means that things that rely on heavy accuracy rather than strengh, I do with my left. I can hit a baseball more often left sided, but am stronger batting from the right. I can make baskets in basketball at a higher percentage with my left but I feel more comfortable with my right and typically shoot with my right...but I often switch while playing and shoot left hooks with my left. I can eat with my right or with my left, but I gotten in habit to eat with my right since I grew up seeing most people eating with their right...eating with my left feels a bit strange. In boxing, I prefer to fight orthodox (right handed). Majority of the things Ive gotten in habit of doing with my right side, but some things I have to do with my left, specifically the writing part.
