i dunno about that code but context has support for positions for years now, in
your case you probably need something
\starttext
\let\CurrentPos\empty
\def\StartPos#1%
{\pushmacro\CurrentPos
\edef\CurrentPos{mypos:#1}%
\dontleavehmode\bpos\CurrentPos
\ignorespaces}
\def\StopPos
{\removeunwantedspaces
\epos\CurrentPos
\popmacro\CurrentPos}
\def\BoxPos#1%
{\dowithnextbox{\hbox{\hpos{mypos:#1}{\box\nextbox}}}\vbox}
\StartPos{x}\input tufte \StopPos
\StartPos{y}\input zapf \StopPos
\placefigure
{}
{\BoxPos{q}{\framed[width=3cm,height=4cm]{}}}
\stoptext
in the *.tui/tuo file you can grep for mypos
