Ah! ok, I also have cua-highlight-region-shift-only t in my Customize
section, so I hit this without trying? But here's a way to repro,
starting from emacs -Q:

emacs -Q
Set Options => Use CUA keys (Cut/Paste with C-x/C-c/C-v)
Unset Options => Use CUA keys (Cut/Paste with C-x/C-c/C-v)
M-x set-variable cua-highlight-region-shift-only t
Set Options => Use CUA keys (Cut/Paste with C-x/C-c/C-v)
<open a file>
S-down S-down down down backspace

or alternatively, use a .emacs containing just:

(custom-set-variables
 '(cua-highlight-region-shift-only t)
 '(cua-mode t nil (cua-base)))
