Repeat doesn't stop even thought theres until?

I am making an SCP game and I am scripting for SCP 173. Here's the script:

local part = script.Parent

part.Touched:Connect(function(hit)
    local hum = hit.Parent:FindFirstChild("Union")
    if hum then
        repeat
        script.Parent.Anchored = true
            print("Player see")
            wait(1)
        until hum == nil
    elseif hum == nil then
        repeat
        script.Parent.Anchored = false
            print("player ignore")
            wait(1)
        until hum
        end


    end)

i am trying to do a repeat but it just doesn't stop. Help appreciated!
