Yes, it is true, because the file is included and it is not anymore like
a recipe that can be extend. It will be searched for a
image_with_graphicsupport.bb append, not image_base.bbappend.

IMHO you can easy reach your goal if you write a packagegroup recipe
where you put all packages you have in the IMAGE_INSTALL of your
image_base.bb. You can then have a .bbappend for the packagegroup in
your BSP layer (and this then works) and you put the packagegroup in the
IMAGE_INSTALL directive of both image_base.bb and
Image_with_graphicsupport.bb.
