We follow the bash behaviour. And the bash behaviour is exactly what 
GRUB does:
address@hidden:14:15:11:~/grub2/bzr/mainline$ bash
address@hidden:14:15:15:~/grub2/bzr/mainline$ export XYZ=x
address@hidden:14:15:19:~/grub2/bzr/mainline$ exit
address@hidden:14:15:20:~/grub2/bzr/mainline$ echo $XYZ

address@hidden:14:15:24:~/grub2/bzr/mainline$
