"Voldemort put a bit of himself in [Harry]."  On the Harry 
end of the connection there is a bit.  On the Voldemort end 
there is "himself".  A scar on one end; on the other, a 
whole head. Add to that the fact that Voldemort is a 
powerful seventyish-year-old Dark Wizard, highly skilled 
at Legilimency, and Harry (in OotP) is a fifteen-year-old 
unable to master Occlumency and I think it is a reasonable 
deduction that Voldemort has the capability, at least, to 
extract much more information from the connection than Harry does.

Even Harry is able to do more than merely sense LV's 
very strong emotions.  During the vision of Voldemort's 
interview with Rookwood, Harry was not only able to hear 
the entire conversation, he could see the scars on 
Rookwood's pock-marked face; he could see the cracks 
and spots on the mirror.  If Harry is able to perceive 
this much detail when he is being Voldemort, it stands 
to reason that Voldemort can see as much, and likely 
more, when he is being Harry.

What is it like for Voldemort, being Harry?  (And that 
question is not irrelevant.  We are never shown Snape's 
inner experience.  Would anyone say, therefore, that it 
is irrelevant?)  The mechanics of the two-way connection 
between Harry and Voldemort are not spelled out, but it 
is canon that there is a *two*-way connection.

When Voldemort is close by or feeling a particularly 
strong emotion, reception is activated on the Harry
end and Harry feels the scar prickle, burn, etc., and 
he feels Voldemort's emotion or occasionally even sees 
what Voldemort is seeing and hears what is being said.

What happens on the Voldemort end when Harry is feeling 
a particularly strong emotion? (He's a pretty emotional 
kid.)  When Harry is tuned in to Voldemort, his scar 
hurts.  Voldemort apparently feels nothing; he doesn't 
realize until the end of OotP the extent to which Harry 
has penetrated his mind.  When Voldemort is tuned in to 
Harry, but not actively trying to implant visions, would 
Harry's scar hurt?  I think possibly not.

Of course, time and space matter in magic and the walls 
and grounds of Hogwarts are guarded by many ancient spells 
and charms to ensure the bodily and mental safety of those 
who dwell within them, but is it absolutely certain that 
Voldemort can never tune in to Harry undetected?  
Dumbledore doesn't seem to think so.  Otherwise, why 
did he shun Harry all through OotP, even refusing to 
make eye contact on the few times when they were together?

So I don't think it is a bit much to assume that LV can 
sense more about Harry than Harry can about LV.  Dumbledore 
does not know the extent to which Voldemort can make use 
of the connection between himself and Harry, and he is 
clearly worried about it. 

*********

Off on a tangent related to the above only as something 
that is not spelled out in the books but which must have 
significance if one really thinks about it:  Scabbers was 
a party to just about every private conversation between 
Ron and Harry from the time they met on the Hogwarts Express 
until his faked death at the hands of Crookshanks.  How
much of that information did he pass on to LV and is any 
of it relevant to the mysteries waiting to be resolved in DH?
