Jerome's excellent post explains this.  Using local with assignment is 
syntactic sugar for a local declaration followed by an assignment. 
Separating the local declaration from the assignment allows you to "see" 
what is really happening:

b = 3  -- modifies _G.b
b = 4  -- modifies _G.b
local a
a = 3  -- modifies local a
a = 4  -- modifies local a
