d is undefined (here is the bug) then applies to c ≠ d ∨ d ≟ false

c ≠ d is always true

d ≟ false is always false

so true ∨ false is always true

-------------------------------

Note: it is not possible to find the reason for d=undefined just from the image.

This would require the ggb-file instead of jpg.
