I understand this. But my experience in the matter has been that if the tests 
cover 100% of the code paths, the incidence of undetected bugs in the code goes 
very, very low.

So, I disagree with "doesn't mean much". Pedantically, it means little, but 
practically, it means a great deal.

(Of course, for multithreading you'd be right - runtime testing is notoriously 
unproductive in finding concurrency mistakes.)
