Kalo damage when all allies are alive is incorrect

For me, the Kahlo attack algorithm remains incomprehensible. Does he deal 135% damage first and only then determine his second move? Then, attacking the team with an active counterattack, he may not survive until the second move. Question two: if Kahlo is the first to use a dead MN skill and revives all allies, will he continue to use their skills during this turn or stop? Or will it deal another 270% damage?
