To reproduce:
emacs -Q
C-h v
M-n
Observe that a variable's name is inserted into the minibuffer; in my
case it's "find-sibling-rules". (It was inserted by
minibuffer-default-add-completions.)
M-p
Now the minibuffer is empty (except for the prompt), and
find-sibling-rules is in "future history".
M-s sibling RET
Surprise: instead of finding find-sibling-rules, this displays a
message: "No later matching history element".
M-n
M-n
Now we have 2 elements in the "future history", but:
M-r sibling RET
signals an error: Wrong type argument: stringp, nil, instead of
finding find-sibling-rules.
Bottom line: M-n and M-p unexpectedly don't search "future history".
Without that, adding all of the completion candidates to "future
history" is a misfeature when the list of candidates is very long.

I suppose M-s and M-r. OTOH, C-s and C-r search "future history" nicely.
Why M-s and M-r don't use the same search functions as C-s and C-r?

Yes, sorry.

I don't think I know the answer.
