Are'nt scripts supposed to run in order?

I have a script I made that detects if a person has any of six game passes. the script is...

print ('mark 1')

local passId = 172986242 -- change this to your game pass ID.

function isAuthenticated(player) -- checks to see if the player owns your pass
    return game:GetService("GamePassService"):PlayerHasPass(player, passId)
end

game.Players.PlayerAdded:connect(function(plr)
    if isAuthenticated(plr) then
        local m = Instance.new("Messsage")
m.Parent = Workspace
m.Text = (plr.Name .. "is a First class customer this flight")
wait(12)
m:Destroy()
else 
    print ('continue')
    end
end)

print ('mark 2')

local passId = 172986990 -- change this to your game pass ID.

function isAuthenticated(player) -- checks to see if the player owns your pass
    return game:GetService("GamePassService"):PlayerHasPass(player, passId)
end

game.Players.PlayerAdded:connect(function(plr)
    if isAuthenticated(plr) then
        local m = Instance.new("Messsage")
m.Parent = Workspace
m.Text = (plr.Name .. "is a Business class customer this flight")
wait(12)
m:Destroy()
else 
    print ('continue')
    end
end)

print ('mark 3')

local passId = 172987173 -- change this to your game pass ID.

function isAuthenticated(player) -- checks to see if the player owns your pass
    return game:GetService("GamePassService"):PlayerHasPass(player, passId)
end

game.Players.PlayerAdded:connect(function(plr)
    if isAuthenticated(plr) then
        local m = Instance.new("Messsage")
m.Parent = Workspace
m.Text = (plr.Name .. "is a Economy class customer this flight")
wait(12)
m:Destroy()
else 
    print ('continue')
    end
end)

print ('mark 4')

local passId = 172987506 -- change this to your game pass ID.

function isAuthenticated(player) -- checks to see if the player owns your pass
    return game:GetService("GamePassService"):PlayerHasPass(player, passId)
end

game.Players.PlayerAdded:connect(function(plr)
    if isAuthenticated(plr) then
        local m = Instance.new("Messsage")
m.Parent = Workspace
m.Text = (plr.Name .. "is a Permanent First class customer")
wait(12)
m:Destroy()
else 
    print ('continue')
    end
end)

print('mark 5')

local passId = 172988022 -- change this to your game pass ID.

function isAuthenticated(player) -- checks to see if the player owns your pass
    return game:GetService("GamePassService"):PlayerHasPass(player, passId)
end

game.Players.PlayerAdded:connect(function(plr)
    if isAuthenticated(plr) then
        local m = Instance.new("Messsage")
m.Parent = Workspace
m.Text = (plr.Name .. "is an Economy class customer")
wait(12)
m:Destroy()
else 
    print ('continue')
    end
end)

print ('mark 6')

local passId = 172987757 -- change this to your game pass ID.

function isAuthenticated(player) -- checks to see if the player owns your pass
    return game:GetService("GamePassService"):PlayerHasPass(player, passId)
end

game.Players.PlayerAdded:connect(function(plr)
    if isAuthenticated(plr) then
        local m = Instance.new("Messsage")
m.Parent = Workspace
m.Text = (plr.Name .. "is a Business class customer this flight")
wait(12)
m:Destroy()
else 
    print ('continue')
    end
end)

print('End execution')


and the output is (I'm in studio's "play solo")

Is it something wrong with the Output or is it supposed to do that?
