I have never used Dialog before, but the problem seems to be that 
"local" variables are simply renamed variables in Mathematica.

Try this: Module[{a}, a]

I do not know why did they choose this solution for local variables ...

I have no idea about how could you get the "local name" of 'a' in the 
example you gave.
