It is related to ConTeXt's multicolumn Output Routine.

No, they are not, the first row (column) is 1 points taller than the second
one, you can test this with TeX.
\starttext
\setbox\scratchbox\hbox{$a_n=\frac{(-1)^n}{\sqrt{n}}-3$}
Formula 1: \copy\scratchbox
Height of formula 1: \the\ht\scratchbox
\setbox\scratchbox\hbox{$a_n=2+\frac{1}{n+1}$}
Formula 2: \copy\scratchbox
Height of formula 2: \the\ht\scratchbox
\stoptext

Because itemize use for the columns key the multicolumns envrionment
where you can force a new column with the \column command.
The internal work for this case is something like in the following example:
\starttext
\startcolumns
$a_n=\frac{(-1)^n}{\sqrt{n}}-3$
$a_n=2+\frac{1}{n+1}$
\stopcolumns
\startcolumns
$a_n=2+\frac{1}{n+1}$ \column
$a_n=\frac{(-1)^n}{\sqrt{n}}-3$
\stopcolumns
\stoptext
No, I don't understand this at all.
I hope my examples helped you a little bit to understand the problems
in your example and why my methods worked.
