Another advantage to this - Snape seemed to have to use the 
Legilimens spell to read Harry's mind, but is good at blocking others 
from reading his own mind.  On the other hand, Dumbledore seems 
proficient at both - he didn't need them to tell him what the vow 
was, but could read it from her mind as she thought about it.

Having promised, as Snape, to protect Draco, he then enlists Snape to 
keep an eye on Draco, to keep Draco from doing something to harm his 
soul.
