Ground targeting aoe at targets target

Does

#show <spell>
suppressmacrofailures
cast @targettarget @gtae <Spell>
cast @gtae <Spell>
cast <Spell>

Function corretly?

As in, I want the macro to cast an AoE ground target at targets target, if false then cast Ground AoE at my target, and if false be able to place the Ground target AoE.
