Measuring, temporarily removing skyshield. Either way blast can be put and hits everything under it regardless of which floor it is. You could stack 10 skyshields top of each other and hit troops on every one of them if they are on same position horizontally.
Don't put models under skyshield and at the top at the same positions.
