No, it is not meant to.

#2 means use any of the variants (in the search string) to
search for any of the variants (in the text being searched).
It is the proposal of this thread.

(#2 was admittedly expressed not so well (I tried to reuse
your two expressions, and the result of combining them was
clumsy.)

Currently, to search for all of the variants (any of them,
indifferently), you must use the base character in the
search string.  You cannot use any of the variants in the
search string, to get the same effect.  Only the base char
lets you search for the class, i.e., use char folding.

(But I think you already realized this.)
