As it stands, it doesn't look like there is one. It appears to be a recreational mathematical toy for the creator to learn things more than it is for others to play with. It's kind of neat nonetheless.
I think I might have made different choices for the reversal calculations, but I haven't really thought about how I'd implement those choices, nor about nigh-insurmountable edge cases, and I'm only vaguely thinking about the "c = a OP b" case, not anything more extreme. The creator may have wanted to make the same choices but found themselves forced down a different path.
Verbatim from the creator: "it is imperfect".

That's perfectly fine. :) I just couldn't find a use case and didn't want to miss it.
It may or may not be intentional, but it could serve to answer what-if questions. If I want a certain outcome, what should the inputs look like?
It's very cool. I wonder if a heuristic in the solver to prioritise changing values by as little as possible would help yield more predictable outcomes?
It would also be cool to be able to add constraints in other cells, like A1 > B1 or A1 + B1 = 5, though then it would really be more like a linear programming solver than anything.
