Question regarding the Execution on Urgot's Ult

Ive been wondering, how does the Execution part on Urgot's Ult interact with revives and after death passives on champions, like Guardian Angel revive, Aatrox Revive, Zilean Revive, and also things like Sion's Passive or Karthus's Passive? Does it still activate those Revives/Passives when they are killed, or do they just die altogether without them going off like it happens when you die to the fountain laser? I'd love to hear it if anyone knows about these.
