No, I didn't try HN+N by myself, so I had to say "perhaps" in my last comment.

For event summary in Creation of Gaia page says

"you'll be able to do a special evolution synthesis with another N of the same kind"

. If this is an original text,  devs most likely considered this upgrade as evolution, so displaying information as-is isn't necessary a bug, imo.
