I wondered the same thing and from what I can tell on T'Internet then yes it seems to be the same thing.
I am going to try the Liberon lathe polish sometime in the next couple of weeks, unless someone more expert on here says don't.
I started with the CA and got some reasonable results for a beginner, but just lately it seems to be "ridgy" no matter what I do with it, so will try the friction polish and wax route and see which I prefer.
