Method of Projections tell us the positions of the views where they are projecting on the Planes. Consider 1st Angle of projection, All the views from a particular direction are projected on the opposite side, while in 3rd Angle of projection, All the views from a particular direction are projected on the same side. Take a case of 2nd Angle of Projections( means object lies in 2nd Quadrant) since the image is to be formed on the planes only that is why we have to keep right side view on the same side from viewing while top view on the opposite side from viewing. This contradicts view placement( i.e. once you are placing on same side and once on Opposite). Same is applicable in 4th Angle of Projection also.
