Ceridwen:
Harry was only safe as long as Dumbledore was alive.  Once he fell from 
the tower and was dead, the spell released.  There is no reason to 
believe that the spell would have remained to freeze Harry to the spot 
if Greyback tore Dumbledore apart, or Draco AK'd or otherwise disposed 
of him.

And a free-moving Harry, angry at the death of Dumbledore, as we saw in 
Flight of the Prince, takes unnecessary risks without fear of dying.  
Facing Snape, who merely blocked his spells, was one thing.  Snape even 
stopped one of the other DEs from Crucio'ing Harry.

But, facing the DEs, Draco, and Greyback on the Tower, alone or with 
Snape as part of his opposition, would have seen Harry dead or horribly 
tortured and possibly incapacitated for book 7.  Maybe he'd get a bed 
beside Lockhart if he lived through it?  Maybe he'd be mangled like 
Bill.  Maybe he'd be torn apart.  But, Harry, facing at least four DEs 
and an untransformed werewolf alone?  I don't think he could have 
pulled off a Rambo on this one.
