The differences are in the noswap and noautomount boot parameters which exist in the forensics mode option. While noswap is a standard Debian boot parameter, the noautomaount is a Kali specific feature, implemented by the /etc/X11/Xsession.d/52kali_noautomount file, shipped in the kali-defaults package.
