This of course shouldn't happen.

Uhm I'm a bit unsure if you understand basic shell scripting.
If you change
if ${use_bg} ; then
to
if false ; then
or
echo "Found Debian background: `basename ${bg}`" >&2
use_bg=true
if you change this use_bg= to false it has the same effect.
And I just tested both now to be sure.
Note that it doestn't count what update-grub outputs or 00_header says
for the real GRUB. Only /boot/grub/grub.cfg counts for it.
If there's no background_image line in it, it will never use one.
