What makes this an infinite loop?

class Photo < ActiveRecord::Base
  attr_accessor :applicable_styles

  before_post_process :setup_styles

  def applicable_styles
    @applicable_styles || setup_styles
  end

  def setup_styles
    @applicable_styles ||= {}

    if is_animated_gif?
      ...
    end

    @applicable_styles
  end
end
