It was interesting watching/reading the 'discussion' between the two posters. While it 'seems' obvious that a 1 amp/120 VAC load on each side of the panel would add up to a 2 amp load on the neutral, what made the concept clear (and obvious) was that the series connection of 2 equal 120 VAC loads across 240VAC would result in zero amps on the neutral - beautiful!
I guess the old adage "Don't confuse me with the facts - I already have my mind made up" strikes again or " I think I know what I thought you said, but what I heard is not what you think you said" or something like that. Great discussion!
