Puppet users - Feb 2014 - puppet random notification confusion

i am being through a exercise on docs.puppetlabs.com
and i am confuse with the notification output. as it shows last message
first and first message at last.
i just need to know why the output notifications are random

here is my .pp file.

@puppet:/etc/puppetlabs/puppet# cat  text.pp

file {'/tmp/test1':
      ensure  => file,
      content => "Hi.\n",
    }
notify {"this is 1":}

   file {'/tmp/test2':
      ensure => directory,
      mode   => 0644,
    }

    file {'/tmp/test3':
      ensure => link,
      target => '/tmp/test1',
    }

    file {'/tmp/test2/insidedir':
      ensure => file,
      content => 'infor put by me',
    }

    user {'katie':
      ensure => absent,
    }

notify {"I'm notifying you.":}
notify {"this is 2":}
notify {"So am I!":}
notify {"this is 3":}

---------------------------------------
here is the output

Notice: Compiled catalog for puppet.mycompany.com in environment production
in 0.55 seconds
Notice: this is 2
Notice: /Stage[main]//Notify[this is 2]/message: defined 'message' as
'this
is 2'
Notice: this is 3
Notice: /Stage[main]//Notify[this is 3]/message: defined 'message' as
'this
is 3'
Notice: So am I!
Notice: /Stage[main]//Notify[So am I!]/message: defined 'message' as
'So am
I!'
Notice: I'm notifying you.
Notice: /Stage[main]//Notify[I'm notifying you.]/message: defined
'message'
as 'I'm notifying you.'
Notice: this is 1
Notice: /Stage[main]//Notify[this is 1]/message: defined 'message' as
'this
is 1'
Notice: Finished catalog run in 0.49 seconds


so the question is why the notification outputs are so random.

Thanks,

MYK
