As others have said, the answer is yes, it's a consqeuence of Ruby's
parser. When Ruby sees an lvar assignment, it initializes the symbol to
nil in the symbol table. Another example of this is:

def foo
  bar = "<3" if false
  bar
end

foo # => nil

Even though 'bar = "<3"' never runs, the lvar still gets initialized in
the symbol table, hence the method returns nil.
