Make it:

   local t = 1

Then the two t are actually different variables (in the current
implementation), and it's not clear to which incarnation the
comparison refers.

Why is it not clear?  Would it be clearer without the continue statement?

The continue statement does not impact the *scope* of variables.  Scoping is lexical -- as written.  Continue is just a restricted 'goto'.
