If Falling Star reduces Sett's HP to 2, then Smoke Screen reduces his Might, does Sett die?

Ruling: Yes, Sett dies. Units with lethal damage (damage equal to or greater than Might) are killed during cleanup.

Sequence:

• Falling Star deals damage to Sett
• Smoke Screen reduces Sett's Might
• During cleanup, the game checks if damage equals or exceeds current Might
• Sett is killed because the damage now equals or exceeds his reduced Might
