How about
"...if the changes do not immediately follow the control that triggered the change in the programmatic reading order."

[Jason] That’s definitely in the right direction. Note that we’ll also have this problem with the concept of relative order as used in 3.2.3. It’s an issue with which the APA working group has been struggling since late last year with regard to new features of CSS. It particularly affects screen reader users, as some screen readers follow the DOM tree order, whereas others seem to follow the on-screen order as defined by bounding boxes of the elements (e.g., VoiceOver under OS X in its default mode).
