In math mode, there *is* an expression state maintained, and that is why \over
and \atop work.
Actually (still oversimplifying), the found commands are saved in a temporary
list,
that is then reprocessed once math mode has ended. And at that stage, an
expression tree is built up.
another way to look at it is to think of each {...} being a subformula, so
{1} \over {2}
are two subformulas combined into one larger subformula
