Well, you don't /have/ to use ². But if there is only one index, it is
much more convenient to write ² instead of ^2. And it even works in
cases like ∫²³₁₂, where the normal writing would be ∫^{23}_{12}. If you
understand the ² as “superscript first order” instead of “superscript
the next order”, it is also what you expect …
