Character Strategy: Han Solo

Han has always had native counterattack ability (35%) which means he'll reach 85% under CLS lead so expect him to counter like Fives. The "each turn" wording is identical to ATF's ability Perseverance which triggers on any individual character's turn (whether friendly, enemy, or self) so it looks like Han should double tap on a counterattack (counter each hit, but double tap on first counter only when multi-hit by someone like Rey, Fives, Dooku) or as an assist.
