Well yes and no IMO. Most bump steer measurements are taken I believe with wheels pointed straight, and if both links are not parallel with the LCA and located inline with ball joints and pivot points, bump steer is present. I suspect its possible one side could be relatively bump steer free and the other side not to be, if any of the three conditions you note are present. I believe once straight-ahead bump steer on both sides is corrected/improved, any steering issues regarding binding, accelerated wear, etc will have already been resolved.
What I can't wrap my head around yet is if both sides could have exactly opposite bump steer problems, effectively canceling out normal observed bump steer issues while driving. work

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
