"All Glory Be to God Alone"

I was looking at "All Glory Be to God Alone" earlier this month, and I noticed a small feature in the last line of the third verse:  "To all the world Your grace extend," sung to this musical phrase from the tune "All' Ehr' und Lob":

The phrase "all the world" is sung to notes of all different pitches (B A G), giving a small sense of this entirety.

(A couple years ago, I noted some other features in this same line.)
