Your subclass has the same name as the parent class, doesn't it?  In that case,
the mangling of your __helper will be identical to the mangling of the parent's
__helper, so the overriding magically works, even though it's a
double-underscored method.

That's a bit tricky, and worth a comment in the subclass...
