Shura's effect?

Blackwing Shure the Blue Flame wrote:

In order for its effect to activate, “Blackwing – Shura the Blue Flame” must be face-up on the field when the monster it destroyed by battle is sent to the Graveyard. This means:
If Shura and the other monster destroy each other by battle (equal ATK), Shura’s effect does not activate.
If Shura is destroyed by a Flip Effect like “Man-Eater Bug,” Shura’s effect does not activate.
If Shura is flipped face-down after damage calculation by a card effect, such as “Desertapir,” Shura’s effect does not activate.
If Shura is removed from play [sic] by battling “D.D. Warrior,” Shura’s effect does not activate.
If Shura is destroyed by an effect after the monster it destroyed by battle was sent to the Graveyard, such as “Michizure,” Shura’s effect DOES activate, and you can Special Summon a monster.
