Human Torch "Flame On" Global Ability

Hi,
Could you please clarify the Human Torch "Flame On" Global Ability, specifically:
1. Is the Human Torch global a separate source of damage from the initial global/action?
(I.e, If I Power Bolt Hulk Green Goliath, and then pay a bolt, does Hulk's ability trigger twice?)
2. Does the target of the Human Torch global have to be the same as the target of the initial global/action?
(I.e, If I Power Bolt an opponents character, can I then pay a bolt to damage my own Hulk?)
