The *list* variables work only in lists.

There’s also \structurevariable and \structureuservariable.

Make sure you use setups for the header, otherwise the variable gets 
expanded only once at the beginning.

Like in:

\setuppagenumbering[alternative=doublesided]
\setupheadertexts[] % empty
\setupheadertexts[\setups{text right}][][][\setups{text left}]

\startsetups[text right]
\rlap{\pagenumber}
\hfill
\getmarking[chapter]
\hfill
\llap{Un Nom}
\stopsetups

\startsetups[text left]
\rlap{Una Person}
\hfill
\getmarking[section]
\hfill
\llap{\pagenumber}
\stopsetups
