Not necessarily, in the case of throw-away temporary variables:

  i = 0
  .. some code which uses i

  .. big gap

  i = 0
  .. different code, different i

You don't care that the two 'i's are bound to the same storage location
unless the value needs to be used after the second chunk of code, and if it
has to persist across that big gap, you should choose a better name than 'i'
:-)
