Also, what I think is that at the time of the player fus ro dah-ing the orb, Vulthuryol is somewhere above, perhaps just, i don't know, sleeping or something, bacause usin the shout on the orb lets out a loud ring that would awaken him (the orb does not contain him, it would be too small anyway. Whether this was the original purpose of the orb or not is another question, but when I encountered him I specifically noticed that shouting at the orb made a sound ring out, and I saw Vulthuryol fly down from the cavern roof.
