Because Emacs' redisplay is unable to keep with the scrolling. Before
23.1, with scroll-conservatively set to a large value, Emacs never
jumped; now it tries no to do it, but sometimes it fails. I think the
relevant ChangeLog entry is this one:
2008-10-27 Chong Yidong <cyd@stupidchicken.com>
* xdisp.c (try_scrolling): When computing the distance from the
scroll margin to PT, try moving some distance past the window
bottom before giving up.
