RAW Glory Red Green node: when Glory triggers it cast a card from exile at the end of turn segment

For the understanding:

I am playing the red/green node with brokhan to use his third to bring Gaea's Revenge 4+ times on the board. Until the third ability is ready i use the lifelink soldiers from march of the multitudes to keep my lifepool up. In case glory triggers by my opponent i have a leyline of singularity in the deck, that will be exiled if i feel i won't need it.

In the last match, i did exile leyline of singularity and glory triggers at End of Turn and while it does it brought back leyline of singularity to the battlefield under my control and destroyed my soldiers and the summoned angel tokens. In the logs you will find that i cast it at the End of turn segment, just after Glory triggers.

Is Glory able to bring back cards from exile (maybe the last one?) Some hidden feature we can use?
