When Carly and Sam both have their hair in ponytails and Freddie has his hands on the ropes, three different camera angles are shown during the live webcast - one is a wide-angle shot that shows all three of them, one shows a close-up of Carly, and one shows a close-up of Sam. But as all three are together in front of the camera(s), and Sam has dropped the remote, there is no one in the iCarly studio to operate the controls that change the camera angles.
