yes, it boots you directly into the installed system just as if you
would have installed GRUB on your harddisk.

No the reference should be (cd) as stated in the manual.
However, I took this post as a cause to have a closer look at the manual
(I am maintaining the GRUB chapter) and unfortunately found
errors ;-((. Here is the correct recipe:
1 Change into a directory in which to create the ISO image, for example:
cd /tmp
2 Create a subdirectory for GRUB:
mkdir -p iso/boot/grub
3 Copy the kernel, the files stage2_eltorito, initrd, menu.lst, and
message to iso/boot/:
cp /boot/vmlinuz iso/boot/
cp /boot/initrd iso/boot/
cp /boot/message iso/boot/
cp /usr/lib/grub/stage2_eltorito iso/boot/grub
cp /boot/grub/menu.lst iso/boot/grub
4 Adjust the path entries in iso/boot/grub/menu.lst to make them point
to a CD-ROM device. Do this by replacing the device name of the hard
disks, listed in the format (hd*), in the pathnames with the device
name of the CD-ROM drive, which is (cd):
timeout 8
default 0
gfxmenu (cd)/boot/message
title Linux
root (cd)
kernel /boot/vmlinuz root=/dev/hda5 vga=794 resume=/dev/hda1 \
splash=verbose showopts
initrd /boot/initrd
Use splash=silent instead of splash=verbose to prevent the boot
messages from showing up during the boot procedure.
5 Create the ISO image with the following command:
mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \
-boot-load-size 4 -boot-info-table -o grub.iso /tmp/iso
6 Write the resulting file grub.iso to a CD using your preferred
utility. Do not burn the iso image as data file, but use the “Burn CD
Image” option of your burning utility.
