I the old days of led typesetting, the mathematicain wrote the paper by
hand, or if available, on a typewriter. Then the typesetter has to
interpret that. Then the communications between the two does not work as
intended, and the corrections are not a convergent procedure.

Therefore the electronic typesetting system TeX was made.

So the answer is probabably that there are several different conflicting
conventions in place, some which belongs to the mathematicans, and some
which belongs to the typesetters.
