no, it's not correct. if it were, he wouldn't have to be told that it must be redone after a coldboot.

lets cut to the heart of the matter. @KiiWii is this technically a jailbreak. I've heard no hacker or dev refer to it as that. they always call it exploit.
Hmm, it’s a weird one. Jailbreak or to escape the jailed confines of a secure system.
jailbreak. Slang term used to describe the action of gaining access to an iPhone's private file system to override some of the device's restrictions. Jailbreakingalso enables an iPhone user to install third-party applications.
even cturt refers to jails:
Jails
We can prove the existence of FreeBSD jails being actively used in the PS4's kernel through the auditon system call being impossible to execute within a jailed environment.
I personally I think of it as an exploit chain that escalates privileges to gain control of kernel. I wouldn’t use the term “jailbreak”.
it’s not perma, but that’s neither here nor there..
At the end of the day.... who cares what it’s called ¯\_(ツ)_/¯
