"On the Run"

I was thinking about "On the Run" yester-day and discovered some significance in the shape of the melody at the beginning of the song.  The first four lines are:

Whatever I do

Wherever I go

The same afterglow

Is keepin' me low

sung to a melody something like this:

The initial musical phrase is repeated exactly as the second and third phrases, and this repetition matches both the "same" in the line "The same afterglow" and the constancy of "keepin'" in the line "Is keepin' me low."
