My guess would be a max_gradient issue.

Designing isosurface functions requires a certain way of thinking, which
may occasionally go against common intuition.

Don't let a mere feeling of "this seems wrong" stop you from examining
the approach closer and trying to understand why it may work nonetheless
(unless of course you have internalized the "isosurface way" of thinking
to such a degree that it is reflected by your gut feeling, but I don't
have the impression that this is the case ;)).
