TrackedSymbols:>Manipulate ???

Please explain, in the light of the Documentation Center page for 
TrackedSymbols, what the option TrackedSymbols:>Manipulate does in the 
following code.  This code is a simplified version of what appears in 
the Demonstration "Least Common Multiple and Greatest Common Divisor":

    Manipulate[
       m=First[u];n=Last[u];
       Pane[Text@Grid[{{"m","n","GCD"},{m,n,GCD[m,n]}}],{500,100}],
    {{u,{1,1},"m, n"},{1,1},{99,99},{1,1}},
    TrackedSymbols:>Manipulate]
