No. Extension tubes that offer AF capability simply mean they have contacts that allow for electronic communication between the body and the lens. They do not have autofocus motors in them or add autofocus capability to a body/lens combination that doesn't have it without the extension tubes.
Please see the following diagram.
Move the focus switch on the lens barrel to the MF position. You will now be able to focus by rotating the front-most part of the lens barrel.
Yes the camera will AF if you have it in a mode that will AF when you press the button. It's a remote button. That's all. I found with my remote it more annoying that if would AF so put it manual mode so it would not focus hunt. But I was not take bird photos but photos at night where there was not enough light to AF.
