Subject: self.some_attribute vs @some_attribute

Hello,

I just finished reading the Agile book. Of course I forgot at least the 
two thirds of what I read. I started reading the source code of Typo, to 
see a real (and Rails) application.

I stumbled upon this snippet of code:

  def crypt_unless_empty
    if password(true).empty?
      user = self.class.find(self.id)
      self.password = user.password
    else
      write_attribute "password", self.class.sha1(password(true))
      @password = nil
    end
  end

is there any practical reason to use sometimes self.password and 
sometimes @password? I thought they were synonyms...
