Yes, this doesn't make much sense. I guess this function check was
intended to distinguish a special element
(INDEX-NAME POS FN . ARGS)
from a sub-alist element
(INDEX-NAME . SUB-ALIST).
The check would make sense, if this function was applied to the cdr of
an element, i.e. check if the argument is a SUB-ALIST. But this is not
how this function is used in imenu.el .
I might have initially (and falsely) determined this as the source of
some bug.

P.S.: There is another dot missing in the documentation.

To \"go to\" a special element means applying FUNCTION
to INDEX-NAME, POSITION, and the ARGUMENTS.
! A nested sub-alist element looks like (INDEX-NAME SUB-ALIST).
The function `imenu--subalist-p' tests an element and returns t
if it is a sub-alist.
