The first two link to the existing footnote but do not appear as footnote (no superscript).
You could fake it with
<sup>[[#fn__1|1]]</sup>.
But I would strongly advise against doing that as the footnote ID will change as soon as another footnote gets added before the one you're referencing.
You can simply repeat the footnote and it will link to the same but add another reference, e.g.
some text ((explaining something))[/m] and [m]some completely different text but same footnote ((explaining something)) will link to the same footnote but reference it with two different numbers.
