Quiz: Issuing successive commands

a sample from last posts:

if paladin.canCast("heal"): 
    hero.command(paladin, "cast", "heal", target) 
hero.command(paladin, "shield") 
hero.command(paladin, "attack", enemy) 
##############################################
        if enemy:
            hero.command(friend, "attack", enemy)
            if friend.health < friend.maxHealth:
                hero.command(friend, "move", {'x':44, 'y':44})
######################################################
        hero.command(friend, "move", {"x": 40,"y": 35})
        if enemy:
            hero.command(friend, "attack", enemy)
###############################################
## and this code is accepted as solution
    if enemy:
        hero.command(paladin, 'attack', enemy)
        inNeed = lowestHealthPaladin()
        if inNeed and paladin.canCast('heal'):
            hero.command(paladin, 'cast', 'heal', inNeed)
        if paladin.health < paladin.maxHealth * 0.5:
            hero.command(paladin, 'shield')    

``` Can you foresee what piece of code will be executed and why? This kind of errors are almost never spotted and corrected, because the code somehow works...
