Probably, I wrote wrong description and title for the guide and it’s misleading. This guide isn’t just for deleting dangerous VMs - duress password can execute any commands, and of course it will run emergency system destruction commands. I will edit guide right now.
Now guide has 2 duress passwords for different situations - either just deleting some VMs, or total system destruction to protect against forensics.
p.s.: if you use live mode, when add removing /usr/lib/dracut/modules.d/40ram-wipe/ in duress total system destruction script - it will speed up emergency system shutdown (otherwise this module will perform a check, which may take several seconds).**
