I think they are.  isearch-case-fold-search is an internal detail of
isearch...

I can't see how this distinction is at all useful for the user.
`search-uppercase' already provides a (the) way to decide whether "mixed
case in the search string [should be] ignored":

    (if (and case-fold-search search-upper-case)
        (isearch-no-upper-case-p regexp t)
      case-fold-search)


In the case of occur from within isearch, the current value of
isearch-case-fold-search will make searching find the right matches--if
occur does *not* look at the case of the input again

    (let ((case-fold-search isearch-case-fold-search)
          (search-upper-case nil))
      (occur regexp nlines))
