I think Sharon's idea was to put as much of the vine into the bucket as possible without separating it from its roots so that the unmentionable chemical could kill it roots and all. I have successfully used this technique with vines growing up inside my huge rose bushes. It is important not to get carried away and use a stronger than recommended solution or it will just burn the tops rapidly and never be transferred down the rest of the vine. You can then pull up the dead vine. Done correctly, this technique never releases any chemicals into the environment.
