Cannot understand "on respawn" when its not the first condition listed?

[GrenFlem]

on join:
    if player is "PLAYERNAME":
        while player is online:
            on respawn:
                if player is "PLAYERNAME":
                    wait 3 ticks
                    execute console command "/attribute PLAYERNAME minecraft:fall_damage_multiplier base set 9"

Im trying to set a player's attributes on respawn, but im trying to make it NOT check every player while the targeted player isn't online.

i feel like there should be a better way to loop a single player while they are online after they join.
