IIUC, columns is a "container" environment for other column environments. Here is an example from my slides: \begin{frame}[label=sec-3-4]{Distinguishing CP eigenstates} \begin{columns} \begin{column}{0.5\textwidth} \begin{figure}[htb] \centering \includegraphics[width=0.9\textwidth]{fig1.eps} \caption{m$_\mathrm{ES}$ for B₋ → cc̄K$_S$} \end{figure} \end{column} \begin{column}{0.5\textwidth} \begin{figure}[htb] \centering \includegraphics[width=0.9\textwidth]{fig2.eps} \caption{ΔE for B₊ → J/ψK$_L$} \end{figure} \end{column} \end{columns} \end{frame} So I would think the overlay specification is appropriate for column, not columns.
