I just updated that page with a more detailed explanation of reduce and
rereduce.
Rereduce must *always* be taken into account, though it can often be
handled implicitly by the same code as reduce.
Here is a simple example of a view in which that is not the case:

Does anyone have an easy-to-understand introduction to/tutorial on the
rereduce argument in the reduce function?
I *sort of* understand why it's there and I have a vague understanding
of how to work with it, but this understanding is just that — vague.
What I would really like to see is a couple of examples and explanations
on how and when it should be taken into account when creating the reduce
function
