Sorry for the confusion. Electricians understand 'side' to mean the same 
'leg' of service, not physical location in the panel. Forgot for a 
moment that we're all not electricians =)

To clarify by using your diagram, the recommendation is to have it all 
on A or all on B.

To further clatrify, we do not use two-phase power in the US for 
residential use. Only single and - rarely - three phase systems. It is 
confusing but that the way it is. In a nutshell, sending two legs of 
power from the transformer on the pole, each 180 degrees out of phase 
with each other, into the home is still single-phase. Just two legs of 
it in a very efficient manner.
