Makes perfect sense to me.  Not sure about them being flat though.  I'll go double check both of my sets when I have another minute.

-----------------------------------
The rods for my Starrett are flat across the end.

 I went and looked.  I was in the back shop slitting some stock to width, and I was right there.  The Craftsman set is flat.  The Shars set is definitely radiused on every rod. I recall using the Shar's to get some dimensions for the rails on a handgun frame and I had to sweep it back and forth to make sure I was getting the dimension.  With a square end I would not have had to do that.
 I thought I had a benefit to the radiused end in my mind, but when I think through it doesn't seem to add up.  Maybe just ease of grinding to length being just a theoretical single point instead of a perpendicular flat.
   

   And this might not be as straightforward as I thought . Those collars at the top only want to rotate about 90° . Might be because the setscrews have flattened the threads but I haven't pulled a screw to see . Tomorrow will be soon enough .
