In the case of forward propagation, these artifacts means you get δyiδx1 for ~free, and in backwards propagation you get δy1δxi for ~free.
Presumably you meant to say something else here than to repeat δyiδx1 twice?
Edit: Oops, I now see. There is a switched i. I did really look quite carefully to spot any difference, but I apparently still wasn’t good enough. This all makes sense now.
I could barely see that despite always using a zoom level of 150%. So I’m sometimes baffled at the default zoom levels of sites like LessWrong, wondering if everyone just has way better eyes than me. I can barely read anything at 100% zoom, and certainly not that tiny difference in the formulas!
Our post font is pretty big, but for many reasons it IMO makes sense for the comment font to be smaller. So that plus LaTeX is a bit of a dicey combination.

It is hard to see, changed to n.
