How is this a tautology?

As I had explained to you earlier, well-defined does not mean matching
reality. Well-defined simply means something is clear and precise and
therefore easy to recognize or understand.

A map with regions clearly defined is a well-defined map. A
well-defined map can depict reality or imagination. Using a
well-defined imagination-based map to navigate reality will have
problem. But that map is still a well-defined map.
