Order of operations are applied regardless of what is applied first. Essentially armor is recalculated according to order after each debuff is applied. Even if you Dice first, the second you apply a stack of the BC debuff then armor is recalculated according to order.

So at 100 armor after Dicing and then 3 autos their armor is now 35.75 (rounded up to 36) -> 100-(15*3)=55 -> 35% reduction -> 35.75

This is evident when you try this against something with less then 45 armor. I tried it against blue golem which has 20 armor and after dicing and then 3 autos it had -25 armor. This means after each application of the debuff it is recalculated and at some point flat armor reduction brought it below zero negating the effect of % reduction.
