The initial value being 'disc' does make this confusing, though I'd
note that the example in the body of the spec [1] and the original
cycle() spec text proposal [2] gets this correct:

  /* cycle between markers for nested lists, so that the top level has
     disk markers, but nested lists use circle, square, box, and then
     (for the 5th list deep) repeat */
  ul { list-style-type: disk; }
  li > ul { list-style-type: cycle(disk, circle, square, box); }

except for the misspelling of disc as disk.
