Why? So that there is a convincing witness that Harry is Voldemort, as I said. I’ve stated elsewhere a number of reasons why he would want some people to believe that.
Then his [Quirrell’s] hand pointed the wand at Bellatrix, and moved in a small circular gesture, accompanied by a quiet, “Obliviate.”
That’s not sufficient evidence that she was in fact obliviated. I can wave a stick and say obliviate too, and no one will be obliviated. Surely Quirrell could manage that as well.
