Mass attack vs rampart and unit underneath

[reelthyme]

If you used mass ranged attack next to an enemy rampart with an enemy unit underneath it, does the rampart take damage two times?

I haven't tested this exact instance but previous encounters suggest if anything is "under" a rampart, as far as damage is concerned that other object doesn't exist. You can stack up several mass ranged or other attacks but simply having a enemy there doesn't stack the damage.
