Yes. The article indicate that placment of the pickup can emphasize different harmonics and phasing. Walter has confirmed that from his experiance and Leo Fendor and Les Paul did much of the initial experimental work. Note on guitars with 24 frets like the S-275, S300, Liberator, etc. theire is a 24th fret to play so the neck pickup isn't located at the "ideal" spot. On single pickup guitars I have always perfered the middle lpickup ocation over the neck location and that is a preferencial thing. Others would disagree and perfer to keep the pickup in the neck position.
I doubt any position that would sound "bad" because of the vast number of combinations but some may sound sweeter than others because of the key one play in, the picking style and use of pinch harmonics, etc.
Actually being very close to the bridge is probably as close to a "bad" spot as you can get. You only get the highest harmonics so it could be a bit thin sounding.
