I'm not disrespecting him so much as his proof-reader and publisher.
It seems "faller" works as well for a definition as does "feller", depending on where one lives.
My link provided the first 100 of 5980 hits. I don't know if all of them are pertinent to the topic since it would require flipping through the pages to see. Your link provided all 25 hits on one page. I had earlier tried those terms as well, but figured the results to be insignificant. A couple of them I'd followed seemed to be from west coast entities, as I recall.
The <a href="http://www.dict.org/bin/Dict?Form=Dict3&Database=wn" target="_blank">WordNet</a> database gives the same primary definition for both "faller" and "feller": 'a person who fells trees'
Good day,
