Can't reproduce it here:
 
   emacs -Q
   M-x load-library RET cus-edit RET
   M-: (custom-group-members 'custom-faces nil) RET

gives me a list of the members of that group, one of which is itself
a group but the rest isn't:

   ((custom-magic-faces custom-group)
    (custom-button custom-face)
    (custom-button-mouse custom-face)
    (custom-button-unraised custom-face)
    (custom-button-pressed custom-face)
    (custom-button-pressed-unraised custom-face)
    (custom-documentation custom-face)
    (custom-state custom-face)
    (custom-link custom-face)
    (custom-comment custom-face)
    (custom-comment-tag custom-face)
    (custom-variable-tag custom-face)
    (custom-variable-button custom-face)
    (custom-visibility custom-face)
    (custom-face-tag custom-face)
    (custom-group-tag-faces custom-variable)
    (custom-group-tag-1 custom-face)
    (custom-group-tag custom-face))
