It's a feature. The most common use for this is when you have some
template where several recipes will need to add some content. Then you
do something like this:

  # Recipe A
  template "/etc/something" do
    variables(Hash.new) if variables.nil?
    variables[:foo] = "bar"
  end

  # Recipe B
  template "/etc/something" do
    variables(Hash.new) if variables.nil?
    variables[:baz] = "qux"
  end

It's definitely surprising when you first encounter it, though.
