This code:

display-posts category=”0″

will pick up any posts which have the category of “0” checked, which is no posts at all on this site.

display-posts taxonomy=”category” tax_term=”0″

will pick up any posts which have any sub-category of “0” checked, which is almost everything on this site as “0” is parent/ancestor to most of the important categories.

This is not a bug, it is actually quite useful but you need to know the difference!!!

we use display-posts quite happily with up to 6 levels of nesting.
