Polarisers reduce all reflections, not just in those situations. See
http://www.scienceandart.org/phototurtorial/macro1.html
"Polarizing filters reduce reflected light from leaves and other
objects in the scene and thereby increase color saturation. The
effect of a polarizing filter works whether you are shooting on a
sunny day or in overcast light. Every photographer should own a
polarizing filter."
This is because the glare is colourless, or white, so reducing the
glare allows seeing the colours underneath.
There is one site that shows two pictures of the same flowers in
shade. One has bright pastel flowers, one darker saturated flowers.
Guess which picture used the polariser?
