This may be true of Auto spacing which I've never used, but it is also true
to some extent of specific spacing. By default, Spacing Before is always
suppressed at the top of a page and Spacing After at the bottom of a page.
The exception is after a hard page or column break or a section break. It
can be suppressed after a hard page or column break (but not a section
break) by enabling the appropriate Compatibility option. And Spacing Before
and After between paragraphs are combined by default in recent versions; in
order to prevent it, you have to enable the Compatibility option "Don't use
HTML paragraph auto spacing." Perhaps if you set the spacing to Auto, this
would still happen even with the Compatibility option enabled.
Auto spacing (as the reference to HTML suggests) is one of the features
introduced in Word 2000 to make Word more suitable for creating Web pages, a
truly horrible idea.
