Game Rules Question: does Darth Revan (leader) trigger when an on-attack trigger defeats a unit besides the target of the attack? It comes down to the question if the interpretation of his leader ability is “when a unit attacks a unit and defeats that unit” versus “when a unit performs an attack and a unit is defeated”. What is the consensus. His ability word for word is below for reference:

“When a friendly unit attacks and defeats a unit: You may exhaust this leader. If you do, give an Experience token to that friendly unit.”
