Final answer:
The contract is intended to remain in effect after Lord Atton and Lord Leo die. The claimant of the throne suggests that the exercise of power will reveal one's true intentions, implying the contract's endurance through changes in leadership.
Step-by-step explanation:
The statement in question suggests that the contract in consideration is meant to be binding even after the deaths of Lord Atton and Lord Leo. A key indicator of this intention is the phrase 'even after Lord Atton and Lord Leo die,' which implies a continuation of the contract beyond their lifetimes. Moreover, the claimant of the throne emphasizes the difficulty in determining someone's true intentions until they have actually exercised power, implying that the contract is intended to endure through changes in leadership.
