this will be equal to something different when inside the anonymous function, the code sets the value of this when outside this function to a variable for reference inside the function

By setting a variable (that) to (this) outside of a scope you can always access it (that-this) in deeper scopes that overwrites (this). Example (pseudo code): A { this_a = this; B { this_b = this; C { this_c = this; doSomething(this_a); } } }
