The commit goes like

0bca49801eac749b6adf39b176b9455566faac85
Author:     Bastien Guerry <bzg@altern.org>
org-clock.el: Implement a new parameter :wstart to define the week start day

-      (setq diff (+ (* -7 shift) (if (= dow 0) 6 (1- dow)))
+      (setq diff (+ (* -7 shift) (if (= dow 0) (- 7 ws) (- dow ws)))

I am not sure if there is any particular reason.
