Do your requirements that he have an external clone in order to follow those instructions still apply?
I recommend that EVERY user have an external clone. Having an external clone means that if you run any troubleshooting procedures, software updates, etc., that you won¡¯t end up SOL if things go badly south.
However, in the specific instance that you are asking about, having an external bootable drive is an integral and necessary component to execute the procedure outlined.
Note that replacing your entire OS IS NOT a Macintosh troubleshooting procedure. When your Mac is having problems, it is very rare that the entire OS needs to be replaced.
Also, to correct something that you posted earlier, a Kernel Panic is usually NOT a sign that you have a software problem. It can be, and you might suspect a software problem if Kernel Panics start right after installing or updating your software, but in the vast majority of instances, Kernel Panics are caused by a hardware problem. (At least in my experience.)
