My head hurt too. I had to think about this and make little paper cutouts.
FYI... Not all suspension designers or race car drivers agree with the original premise above. But if you look at the super trick blade anti-roll bars you'll see that many of them are adjustable only on one side.
What gets confusing about this discussion is that we are talking about one thing (lever arm length and the distance the lever arm travels) and then trying extrapolate that into independent forces acting on each side of the spring. You cannot look at each side of an anti-roll bar as acting independently. Its all ONE linear rate spring.
BTW... Carroll Smith generally agreed with this although he thought that in extreme long suspension travel situations where both wheels were traveling in the same direction (i.e. a car going over a speed bump) you would see some asymetry. But this would be irrelevant in a racing situation.
