No. It limits the addition of undo-boundaries to those buffers that have
changed in at the same level of recursion. So, for example, undo will
function in mini-buffer during completing-read, but changes in the
mini-buffer will not result in the addition of undo-boundaries to
buffers that changed during the command that lead to the
completing-read.
