You can the answer in the big manual (cont-enp), it explains the symbols
are defined with \definesymbol and the counters values (n, r, r ... keys)
with \defineconversion.

If I understand the source correct it should begin the itemize with the
level you give with the start value, with the value 2 in your example the
outer itemize group should start with itemlevel 2 and we should get
the dash symbol as item marker but either this did not work I am wrong.

I tried this with the following example but the output off both items
are the same.

\starttext

\startitemize
\item Text
\stopitemize

\setupitemize[start=2]

\startitemize
\item Text
\stopitemize

\stoptext
