The 'Profound' Answer

One thing that has deeply confused me about OOTP is the scene where 
Voldemort possesses Harry. It seems that Voldemort is indicating to 
DD that if he kills Harry, whilst Voldemort is resident within him, 
he will kill them both. He is taunting DD, because he thinks that 
whilst DD could finish him once and for all, DD's love of Harry will 
prevent him making such a sacrifice.

But in PS, Voldemort was resident in Quirrell, and when Quirrell 
died, Voldemort's spirit lived on.

Perhaps, the link between Harry and Voldemort is so strong that if 
you kill one of them, the other will die. This may be the 
more 'profound' answer JKR is referring to. This is further supported 
by the prophecy and DDs confirmation to Harry that in the end one of 
them must kill the other. THis may be the only way to break the link 
between them.
