I don't want to get into an argument about good alt text, but I think 
that the issue here really is that you are willing to make assumptions 
about what sighted people will get out of looking at this ambiguous 
icon, but want to be perfectly clear for those who use the alt text.  
Does the visual rendering of the icon really say what you suggested?  
I'd say that the text on the icon will be enough for an person already 
familiar with WCAG, but that the icon doesn't have enough information 
for those who aren't.

This is not new.  JAWS 4.0 would as well.  It is not the default 
behavior, so as a result I have a low expectation that title will be 
read and therefore don't count on it to convey meaning.
