Did blizz change it to where ready for war also carried over when you faction changed.I remember seeing in a blue post that only 7th legion/honorbound rep would as far as progress for allied races.The only reason i ask is last night i faction changed horde to alliance just to unlock Dark Iron i already had reputation at exalted but when i finally logged in it gave me Ready for War achievement and i could right away do the quest for Dark Iron Dwarfs which i did and i have not done a single quest on alliance side since faction changing just that quest line.
