"All Mankind Fell in Adam's Fall"

When I transcribed "All Mankind Fell in Adam's Fall" last year, I noticed a few instances where portions of the text that mention the fall into sin correspond to descending phrases in the tune ("Wenn wir in höchsten Nöten sein").  As a side note, the tune is oddly formatted.  There are only four measures, but each of these has either twelve or fourteen beats.  This gave me some problems in making examples of the notation.

"All mankind fall in Adam's fall" (in the first verse) and "As by one man all mankind fell" (in the fifth) are sung to the first musical phrase:

The end of this phrase descends, musically representing the fall into sin that's mentioned in the text.

And "From one to all the curse descends" (in the first verse) is sung to the third phrase:

(I didn't notice this until I made my own notation [because it's divided in the hymnal], but there's a cross inscription here.  I don't think it has any connection to the text though.)

Here, the descent in the tune represents "the curse descend[ing]."
