Two ToCs in a document?

Question

I want to have a first level ToC in the beginning of the document, and full ToC at the end. I'm using titletoc.

There's a similar question but it is actually about printing ToC by parts.

I expected to be able just to call \tableofcontents twice in a document:

\documentclass{article}

\usepackage{titletoc}

\begin{document}

{
  \setcounter{tocdepth}{1}
  \tableofcontents
}

\section{H1}
\subsection{H2}
\section{H1}
\subsection{H2}
\section{H1}
\subsection{H2}

{
  \setcounter{tocdepth}{2}
  \tableofcontents
}

\end{document}

but it doesn't work.
