Declaring variables for event handlers

In this video the variables label, li are declared locally and not globally. Why is it that when i declared these same variables globally the out come was not the same? meaning shouldn't it work the same if the variables are global? can someone explain what happens regarding the value of the variables in both instances and how that affects the output?
