Arpeggio Notes

Hey all,
I have a slight problem deciphering arpeggios on a guitar. I had experience with other instruments, but I just want some clarifications.

I looked at http://www.all-guitar-chords.com/arpeggio.php to view the C Major Arpeggio and the notes to be played are C-E-G (typical 1-3-5)

Yet on that site,if i start on 'Fret 0', it doesn't include the G on the low E string. So they pick out this:


-------------0----------
-----------1---1------------
---------0-------0--------
-------2-----------2--------
----3----------------3-----
--0--------------------0--

So why isn't the G note on the low string played? From my understanding, all notes of chord should be played as a broken chord.

I hope this post made sense, and I apologize for my tablature, I'm more familiar with musical notations :)
