This is what I cannot understand.

If the Feminine, and Masculine, Ordinal Indicators (U+00AA, and U+00BA,
respectively) were written in the same fixed-pitch font as the surrounding
text, they also would occupy one cell, each, won't they?

As Frank had written in both of his own drafts:

I think, those are good reasons not to take the glyphs in the Siemens
Nixdorf 97801-5xx Benutzerhandbuch too seriously -- good reasons to unify
these characters with the above-mentioned U+00AA and U+00BA. The only
reason, IMHO, not to unify them would be existence of a character set
containing different glyphs both for the proposed characters and the
existing ones -- as Rick has already noted.
