scroll_past_end, when set to false, is not respected in distraction-free mode, as of build 2117, under Windows XP at least.

For the sake of reference, the url you mentioned is http://www.sublimetext.com/docs/2/distraction_free.html
I now regret I did not look it up properly myself, thank you for the hint
