The Nemeth/UEB Guide seems to say that the commas should be in Nemeth code, even if they could belong with the sentence structure. While digging for examples, I found the handout for "Testing Our Patience" webinar date 11/13/2018. For problem #25, the commas for "where v = initial velocity in feet per second, h = height..." are in UEB.
The commas in your example should be the dot 2 Nemeth literary comma. Nemeth Code is used for these because they occur between technical items like equations (or before a word that will be paired with a single-word switch indicator). The dot 2 comma from the Nemeth Code will be used because each comma follows a word, just like in the example you referenced from “Testing Our Patience.”
Thank you very much for your astute and clear question!
