The blocks at the edge of the quilt are more important as far as having no bias edges, but even the individual blocks should be no bias edges if possible so that it's easier to keep them all in line. Quilters rarely finish a quilt at one sitting and all the movement of the block can pull it out of square if there are bias edges. My guess is that we can't totally prevent bias on block edges, but I try to do it to give myself a better chance of keeping the whole thing straight later.
