If you are required to sew two or more seams to make a section that then needs to be sewn to a block that is cut to for example, 4.5", then you need for the pieced block to finish at 4.5". Depending on fabric and thread and how many seams you are sewing, it can make a difference if you don't use a scant 1/4".
If all the blocks are pieced, then a consistent seam will work, but as MadQuilter said you may lose a point or two.
