I don’t agree. It’s not that bad. You could have drawn the arrow from the bottom to the right without an intersection and it wouldn’t look that wrong. The issue is y being fed in from the left. Please don’t make up flaws not present in the current fold. The actual issue is bad enough in my opinion.
