Another try:

Can someone explain why

\setupitemgroup[itemize][broad,joinedup,packed,autointro]
\setupitemize[itemalign=flushright]
\startitemize[n,repeat]
\item level a
\startitemize[n,repeat]
\item level b
\startitemize[A][prefix=no]
\item level c
\stopitemize
\stopitemize
\stopitemize

yields:

1. level a
    1.1 level b
        1.1.A. level c

rather than

1. level a
    1.1 level b
        A. level c
?
