Subject: attr_* position in a class and their results

Hello,
I was playing with instance variables when I made up those two classes :

class Vartest_before
  def init
    @instance_variable = "I belong to the instance"
  end

  attr_accessor :instance_variable

  def instance_variable
    @instance_variable = "Forced"
  end
end

class Vartest_after
  def init
    @instance_variable = "I belong to the instance"
  end

  def instance_variable
    @instance_variable = "Forced"
  end

  attr_accessor :instance_variable
end

Now when using them, here are the results (# =>) :

a = Vartest_after.new
a.init
b = Vartest_before.new
b.init

puts a.instance_variable # => I belong to the instance
a.instance_variable = "Changed"
puts a.instance_variable # => Changed

puts b.instance_variable # => Forced
b.instance_variable = "Changed"
puts b.instance_variable # => Forced


I don't understand what's happening :/ Can you ?
