OK, you are, of course, right. The output of the query in QuiP is as follows:

   <out>
     <one>True</one>
     <two>False</two>
   </out>

If I remove the curly braces, I get:

   <out>
     <one>$a == $a</one>
     <two>$a == $b</two>
   </out>

So the output I posted did not match the query I posted. I'm not sure what 
I did while writing that email, but the query works properly in QuiP.
