zgirnius:
This is my pet theory as well. I have a slightly different version of 
it. I think Snape is still bound by the Unbreakable Vow to protect 
Draco, and is thus now in the unenviable position of needing to protect 
Draco from Voldemort. This is something he simply can't do in the long 
run. He needs Draco off his hands and safe with the Order.

If Draco does not figure out Harry was there, heard Dumbledore's offer, 
and saw Draco lower his wand, I expect Snape will tell him. And will 
subtly encourage him to seek Harry out.
