Plumbing Drawings

(OP)
When reviewing a set of plumbing drawings and the detail indicates a change in size of the water line is it important where the location of change occurs if the line only supplies one fixture? I am reviewing a detail that indicates a 2 1/2" DCW supplying a group toilet an arrow indicates the copper line changes to 1 1/2" near the manifold and then 1" supplying the fixtures. They all occur below a valve supplying the group toilet. I would think where the arrow points at the copper line is where you would make the change. If it's off 4' or 5' from where the arrow is shown will it matter? The plumber is stating it doesn't matter where the change occurs, if its off a few feet, that the arrow indicating the pipe size is not meant to be the location where the downsize occurs. So how would I know where the change is to occur on the line?
