What's the purpose of joining it with "pb"?

if the proper clause was in place, ooddles of purpose ... it wasn't until
after I upgraded to the newest code that Tom put the fix in for, and it
was *still* causing problems, that I clued into the fact that the AND
clause that was supposed to be associated with 'pb' *wasn't* there ...
For the whole time we were debugging this, none of us clued into it :)
