Q:

Additional page with overlays in notes

I am trying to use overlays inside the notes of my presentation. This is needed to be able to explain a tikzpicture with overlays step by step. My current approach seems to add an additional page when the notes contain an overlay.
Consider the following MWE which uses a simple list instead of a tikzpicture on the slide itself:
\documentclass{beamer}

\usepackage{pgfpages}
\setbeameroption{show notes on second screen}

\begin{document}

\begin{frame}
    \begin{itemize}
        \item<1-> Test
        \item<2-> Another test
    \end{itemize}

\note{
    \begin{itemize}
        \item<1-> Test
        \item<2-> Another test
    \end{itemize}
}
\end{frame}

\end{document}

What am I doing wrong? 

A:

Instead of manually creating the overlays on the note page, let beamer do it for you:
\documentclass{beamer}

\usepackage{pgfpages}
\setbeameroption{show notes on second screen}

\begin{document}

\begin{frame}
    \begin{itemize}
        \item<1-> Test
        \item<2-> Another test
    \end{itemize}

\note[item]<1>{Test}
\note[item]<2>{Another test}

\end{frame}

\end{document}
