Starlight road

Here is the thing.Starlight road only summons a Stardust Dragon if it can destroy the card that causes the destruction of 2 or more cards on your side of the field so if it can't destroy that card does the negate still count?I think it does but gotta make sure.

You mean like heavy>Starlight>Dark Bribe situation ?

I was thinking like :

Enemy has EH absolute zero i got 2 monsters 2 traps (1st starlight 2nd compulsory evacuation device).I use the CED on absolute zero so he goes to extras tho his eff to destroy all monsters activates.Then i use starlight road but absolute zero is in the extras so can i destroy him and SS stardust or not?And if i can destroy him in extra deck what if i had trap hole or smt else that will bring EH absolute zero to the grave?Guess i will only negate the "destroy all monsters" eff only and wouldn't be able to SS stardust if absolute zero is in the grave/removed from play.
