They are two distinct meanings/senses, thus using one to comment on the other is an equivocation.
To use your example term, it would be akin to saying, "The theory of gravity is false because gravity means a matter having great weight and the theory of gravity has no defined weight."
A clearer explanation would be thus: Evolution in the field of biology refers to the change in alleles in populations of biological organisms. Evolution in the sense that Nudger used it the second time simply means change, but not of a specific type. All organisms are undergoing change all the time, but the change which biology terms evolution is not occurring all the time, as changes in alleles in populations only occur at the birth / conception of a new organism. Thus the two meanings of evolution are distinct and Nudger was using two different definitions of change in the same comparison.
Another useful example. We began to refer to evolution in this way -after- theories of evolution had already been described....as they predated our contemporary understanding of genetics. The term biological evolution is certainly more limited, but also not the current theory of evolution, there were competitors even in that subset, lamarckian evolution for example. They were wrong, and yet the observation that all theories of evolution attempt to explain remained to be explained.
The word itself has an even longer history than it's use in this way (unfolding, unfurling, turning etc). As I said at the start, I can't help the way things sound..and I can even see why they may sound that way. Nevertheless, there's no equivocation required for them to sound that way, and a given theory of how is not the what.
