You can’t, markings are only reliable when you use them in the header of footer of the page.
To access the values of a heading you can use the \structurevariable and \namedstructurevariable commands.
\starttext
\chapter{Chapter}
A: \doifsomethingelse{\namedstructurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}
B: \structurevariable{title}
\section{Section}
A: \doifsomethingelse{\structurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}
B: \structurevariable{title}
\subsection{Subsection}
A: \doifsomethingelse{\structurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}
B: \structurevariable{title}
\stoptext
