After being told Sanderson was previously given life, Judge Martin Joy asked at an earlier hearing: "How come he is free?"
Andrew Espley, defending, said a second life sentence would be "an exercise in futility", as Sanderson would only be released if the Home Secretary decided it was safe to do so.
DC Tony Hatcher, from Kent Police, said: "This is a good result which means someone who was a very serious threat to the public has now been taken off the streets.
"Although Sanderson could be eligible for parole in five years he will have to clearly demonstrate that he no longer presents a danger to the public before there is any chance of him being released.
"There is every possibility that Sanderson will remain in prison for a very long time."
