Clarify vs. Better Clarify
Solution 1:
The question involves a confusion between the act of clarifying and the thing being clarified.
It is generally true that clarifying X makes X better. In other words, the X itself is usually better after the clarification than before. The clarification, as distinct from the X that is being clarified, however, cannot be said to be either better or worse, unless there is some other clarification that we are comparing it to.
So for the locution better clarified to make sense, there needs to be a context that involves two (actual or possible) acts of clarification. For example, suppose that something that was unclear has been clarified to some extent: it is now clearer, but still not very clear. One can then meaningfully ask for it to be 'better clarified', that is to be made still more clear.
