Negative Time Iteration (billwadge.wordpress.com)

It's interesting that author has chosen to time-reverse Fibonacci sequence, which is cleanly defined on negative values (although alternating signs are somewhat unusual)

Then they start to talk about imperative programming and its inability to reverse time, completely ignoring the fact that many mathematical functions defined by recurrences, like factorial, are irreversible.

Wadge is a mathematician, so he knows that. Presumably he simply chose an example that fits the material.
