The White Stripes' "I Can Learn"

A few days ago, I listened to the White Stripes' White Blood Cells, and I noticed something about a melody in "I Can Learn."  Near the end of the song, there are the lines "Falling down / Is no longer around."  The "Falling down" is sung to a descending phrase (E B G#), so there's a musical representation of that descent.  The end of "Is no longer around" is sung to an ascending phrase (E G A A# B).  It's as if descending further is no longer possible (because "Falling down / Is no longer around"), so the melody has to rise at that point.
