The History Brushes effect is like cloning from a different undo step.
In this case, evaxebra does a gaussian blur, undoes, and then uses
that blurred image as a source to 'clone' from using the History
Brush.

If I wanted to follow this tutorial, I would, instead of 'gauss blur;
undo; select history brush; paint with history brush' do 'gauss
blur;edit->copy; undo; paste; new layer; layers->mask->add layer mask
(initialized to black); then paint with white and the opacity she
specifies.'. Since the selection needs to be preserved, I'd need to do
that at the start (selection->save); and before painting, load it back
in (channels dialog, rightclick on saved channel,  channel to
selection).

You should also be aware that the behaviour of Gaussian blur may not
be exactly the same in this situation. Experiment.
