Lorel responds:
I'm sure that Snape is much more skilled at nonverbal spells than the 
typical wizard, probably in great part due to his ability to focus 
his mind as a highly accomplished Occlumens. I have no doubt that 
Snape is powerful enough to AK nonverbally, and would indeed be able 
to say the words to the killing spell while actually casting another. 
Why say "Avada Kedavra" when you don't need to, unless it's to be 
sure that you're heard saying it?
