See completion-at-point:

      (let ((newstart (car-safe (funcall hookfun))))
              (and newstart (= newstart start)))

so basically every command following completion-at-point calls HOOKFUN
to check if start matches, in this case it doesn't need the completion
table. Hopefully There will be more places to optimise if studying
minibuffer.el in more details.
