I'm Confused... Help me ?

I am confused over 2 topics, one is regarding LocalScripts and the other is regarding or in if's.

the only difference I know about a LocalScript is that not every service can be used in LocalScripts (Player Points as an example), also, we can use LocalPlayer in LocalScripts. But I have a small confusion. Would it make a huge difference if I put this code (below) in the Workspace instead of StarterPack:?

game.Players.PlayerAdded:connect(function (p)
    print ("Hi there, "..game.Players.LocalPlayer.Name.."! Welcome to _______"
end)

First confusion over

Next, I have the following script:

permission = {"fahmisack123","A380Guy","ismailtheboss"} 

texture = "www.roblox.com/Gem-Tycoon-VIP-Admin-shirt-item?id=129892951" 
texture2 = 157283455
function checkOkToLetIn(name) 
    for i = 1,#permission do 
        -- Convert Strings To All Upper Case, Otherwise We Will Let In 
        -- An Example Would Be "Username"
        if (string.upper(name) == string.upper(permission[i])) then return true end 
    end 
    return false 
end 

local Door = script.Parent

function onTouched(hit) 
    print("Door Hit") 
    local human = hit.Parent:findFirstChild("Humanoid")
    if (human ~= nil ) then 
        if human.Parent.Torso.roblox.Texture == texture or game:GetService("GamePassService"):PlayerHasPass(hit, texture2) then -- Confusion Here
            Door.Transparency = 0.6 --This Means How See-Through The Door Is
            Door.CanCollide = false 
            wait(3) --This Is The Length In Seconds Of How Long The Door Stays Open
            Door.CanCollide = true 
            Door.Transparency = 0 --This Means The Door Is Solid And You Cannot See Through It 
            print("Human touched door") 
        elseif (checkOkToLetIn(human.Parent.Name)) then 
            print("Human passed test") 
            Door.Transparency = 0.7
            Door.CanCollide = false --This Means The Door Is Not CanCollide And You Can't Walk Through It
            wait(3) --This Means How Long The Door Stays Open In Seconds
            Door.CanCollide = true 
            Door.Transparency = 0 
        end 
    end 
end 

script.Parent.Touched:connect(onTouched)

In Line 20 (I think), I have an or. This means if the player has the GamePass, but not the shirt, the door will function and vice versa. but what if BOTH are to be true? Would the door still function?
