If it were additive, assassination would be behind because when 130%X is even with 100%Y, 230%X is behind 200%Y. As long as spec X at 130% (assassination) is equal to spec Y at 100% (combat), they will be even for all multiplicative buffs. No matter how you start at 120k, doubling it is always 240k. This does not mean they are currently equal, but that has nothing to do with the "nature" of assassin's resolve.
