Okay, the problem is the statement
(move-to-window-line -1)
in `gnus-article-next-page'.  If `scroll-margin' is set and greater than
0 it will lead to a recentering.  This is usually countered by
`gnus-article-next-page-1', but not at the end of an article where
`gnus-article-next-page-1' will not be called.

The problem can be circumvented by changing the above statement to
(move-to-window-line (- -1 scroll-margin))

Let me know if the recentering behavior will stay like it is now, then I
can report this to the Gnus maintainers.
