Dear PEP,
As a student of TS Eliot and as a person aware that Ash Wednesday just occurred (Feb. 26), I can dig it.
I would love to know more about the source of your friend's understanding about the designer's intention to have the golfer pay attention to the second ball on the two-ball putter. Personally, I have pretty good reasons to doubt that the designer had any such intention, and has no theoretical understanding of why such a focus may help.
The history of this type of putter design suggests that the actual originator of the idea was someone back around 1974. The Callaway / Odyssey two-ball putter is simply a slightly modified copy of the earlier Pelz three-ball putter from the 1980s. Pelz claims his design is based on visual science of some sort, but he has never said what sort or talked about it. His putter was deemed illegal. The Odyssey two-ball skirts around the Pelz design problem.
Frank Thomas discusses the relation between the Two-ball design and the ealier Pelz design here in this Q&A in Golf Digest:
"Q: Back in the 1980's someone built a putter with either two or three half golf balls mounted in line in back of the face with a look similar to the new Odessey 2-ball. I think D.A. Weibring and several others used it on tour for a while. That putter was declared illegal by the USGA (I think). What makes the Odessey 2-ball putter legal compared to that one? -- John Putman"
"A: John,
The three ball putter, introduced by David Pelz Research in the mid 1980s, came in two versions. The one with a small face and a large flexible wing at the back was declared non-conforming because the distance from the toe to heel was considerably less than the distance from the front to the back (see Appendix II Rule 4b. Dimensions.) The other version, with a large rigid face, conformed and it was grand-fathered after the rules change in 1984. The Odyssey putter does not have balls but flat discs and as a consequence would not be treated the same as the facsimile of golf balls (see Appendix II Rule 4a. Plain in Shape in the Rules of Golf.) For an in-depth explanation of the interpretation you need to go directly to the USGA, but this information may be confidential."

As it happens, it appears someone ELSE entirely designed a two-ball putter even before Pelz, and I recall seeing an ad for one in a golf magazine from about 1973 or 1974. So, in reality, I believe that the real designer just had one of those ideas and stuck golf balls on the back of a putter, and later we end up with the Callaway two-ball with stupendous claims about how it is a deliberate design.
If your friend has some info I can chase down, I'd love to find out I'm wrong about this.
Regardless of the intention or lack thereof of the two-ball designer, I'm not surprised that using this putter that way seems to help. Focusing on the second ball does not so much move focus off the putter's front ball as it takes focus off "hitting" the real ball. This removal of focus from hitting the ball also makes the interior feeling of the stroke movement paramount, and tends to "blind" the golfer away from using the eyes during the stroke. Those are just the two sorts of foucs (interior feel of the stroke and parking vision while the stroke takes place) that facilitate making an accurate stroke, with the pivot still and the lead-side shoulder lifting accurately with dead hands towards a "waiter's tray" end position.
Eyes are the enemy when it comes time to pull the trigger on a putt. You should find that with just a modicum of effort, you can aim the putter face and settle into your setup and then just close your eyes and putt blind with wonderful accuracy.
It's really about managing your body and if focusing on the second ball helps, that's fine. But remember, having a putter that visually attracts your attention in the first place is not a good idea. The two-ball, even used as you describe, definitely attracts the eyes first, even if you then can park vision on the second ball for the stroke. Personally, I'd rather have a "plain-jane" putter that does just what it is supposed to do, and let me get down to the brass tacks of managing the body for an accurate stroke movement.
Thanks for the kind words, and I hope you ask many questions going forward and contribute many ideas.
Cheers!
