Nice tutorial, but, you don't need both A-perms for 4LLL. Just one will do, to swap the corners opposite the headlights. So 16 algs not 17!
Yes; you are correct. However, if the one you don't know came up, you would have to do the other A-perm and then the H-perm instead of one alg. I think it's better to know both of them early on; so I have them both listed. They are also mirrors, so it's easy to learn both.
