Yes, he did. I remember the article from a long time ago. The theme of the
article was how you could improve efficiency by folding the element. It
raised the feed impedance and therefore reduced losses. I do not have the
article at hand but I do remember it. If it was a QST article then it will
be in their online archives.

Did he actually claim that or that the effect of the ground loss was
reduced? I dont have a reference handy.
