its like:
ungor raiders would do the same thing at the same time as Desecrated Temple
EG 2 damage are assigned on it, then next u applie the 2 damage on it.
NOW it will leave play and you are able to use the actions of both cards.
but u were talking about an actionchain
here it is a bit the same: the opponents chain is made of steps too
whenever he/she would kick ur card, he/she would have to risk, that you are using the action

B. Action Window
1. Players take turns putting Triggered Actions that have met their trigger condition since the last Action Window on a chain, starting with the first player (the Triggered Actions also must have met their trigger condition this turn) and continuing until all players pass
-After this, players may only trigger a Triggered Action if it has met its trigger condition since the beginning of the Action Window, and they must do so at the first opportunity (adding it to the next chain, or starting a new one)
2. Players have the opportunity to play actions (starting with the active player, these will either start a new chain or be added to an existing chain if any Triggered Actions were triggered during B-1)
-Choose targets, then pay all costs. If this triggers a Constant or Forced Effect(s), [Go to A]
-This continues until both players have passed consecutively
